Re: [Paraview] Plot selection over time for threshold

[Jairaj Mathur]

Hi Aron

I tried your method and created the trace. When I go to the python shell
and run that python macro, it says that the custom filter I had created
does not exist. My custom filter consists of 2 calculator filters, each
calculating different things. To create that custom filter, I selected both
the calculators on the pipeline browser, right click-> create custom
filter->finish.

To create my python macro, I first load up my .vtu files in the pipeline
browser, hit apply, then I start trace. I add my custom filter, follow
Kenneth's procedure to obtain the plot over time, then I hit Stop trace.
Then in the script generated, file->save as macro.

Re: [Paraview] Plot selection over time for threshold

[Aron Helser]

Hi Jairaj,
This is exactly what the 'trace' and python macro functions are for. Take a
look in the Tools menu, and choose Start Trace. If you check the 'show
incremental trace' button you can see it's recording a python script as you
take actions in the GUI. When you've completed your steps, you can choose
'save as python macro' and you'll get a button that can repeat the steps.

To go more in-depth, look for information on python scripting in Paraview!

Re: [Paraview] Plot selection over time for threshold

[Moreland, Kenneth]

Jairaj,

I’m not sure what exactly you mean by “the threshold,” but there are many ways 
to plot the average of a threshold-selection of cells over time.

The most straightforward way is to open up the Find Data dialog box, select the 
cells you want to plot, and then create a Plot Selection Over Time filter. 
Specifically, here are steps that will do such a plot:


  1.  Open your data in ParaView. Apply.
  2.  Open the Find Data dialog box (Edit → Find Data or click the toolbar 
button on the top toolbar).
  3.  In the top row, set the left combo box to either “Cell(s)” or “Point(s)” 
depending on whether your data is cell or point data. In the longer combo box 
to the right, make sure that your data is selected.
  4.  In the second row, set the left combo box to the field you want to 
threshold on. Change the next combo box to say “is between”. This will create 
to text edit boxes where you enter the minimum and maximum values of your 
threshold range.
  5.  Click the “Run Selection Query” button. This will select all cells or 
points matching your threshold.
  6.  Click the “Plot Selection Over Time” at the bottom of the Find Data 
dialog box. This will create a filter in the pipeline browser.
  7.  Close the Find Data dialog box and click the Apply button.

Re: [Paraview] plot colors: function value -> RGB tuple

[Moreland, Kenneth]

You can achieve this by writing making a filter that creates a 3D vector field 
where each vector represents an RGB color. If writing out floating point 
values, the color channel values should be between 0 and 1. You can then render 
this 3D vector field directly as colors by turning off the “Map Scalars” 
display parameter. “Map Scalars” is an advanced option, so the easiest way to 
find it is to type “map” into the search bar at the top of the properties panel.

Subject: [EXTERNAL] [Paraview] plot colors: function value -> RGB tuple

Hi everyone,

I need to plot complex-valued functions over various domains, and instead of 
splitting the values into real and imaginary part (or absolute value and 
angle), I would like to use a "2D colormap" approach as sometimes suggested for 
complex-valued functions (see, e.g., [1]).
As a lowkey approach of getting this into ParaView, I was wondering if it's 
possible to create a filter that takes a point value (or two), runs it through 
some specified (Python) code, and uses the returned RGB tuple for rendering the 
plot.

Any hints?

Cheers,
Nico

[Paraview] Plot over spline or intersecting plane

[Scott, W Alan]

I am trying to figure out how to plot over more complex surfaces than a 
straight line.  Say a user wants to plot over a curved line, with the line 
matching the inside surface of the can.exo.  Can you now do this?  How would a 
user control the line?

Is the Plot On Intersection Curves filter what I want?

Thanks,

Alan

[Paraview] Rescaling axis in paraview plot

[Amine Aboufirass]

Hi All,

Does there exist any way to rescale x-axis values for a Time history 2D plot in 
paraview? I am seeing some properties with log scale and custom data in the 
properties window but heres the issue:

1) Log scale is not what I am looking for. I am looking to rescale my data 
and show x-axis going from 0 to 1 rather than 0 to 100

2) Custom data for bottom axis will truncate data that is not part of the 
range defined by the user. I am looking to actually rescale the plot in one 
axis based on the new range.

3) No additional filter exists that I could further apply on my current 
plot to play around with the axis ranges.

Does anyone know how to do this without necessarily using macros? Thanks.

Re: [Paraview] "Plot Data" filter has problem with negative values

[FERHAT HAMIDA Abdelhak via ParaView]

I see that restarting the application to make the new settings taking effect is 
disturbing since this does not happen in all cases. In what I have tested, this 
only happen when the saved setting view have LeftAxisRangeMinimum strictly 
positive  (not zero) with LeftAxisLogScale enabled.
Now, if I have to give suggestions:    - This case has be explored, perhaps 
patched.
    - Give to the user the possibility to save the settings in his his 
workspace, in different names, not as default. In this manner, one can try 
severall settings on the same plot and do not alter other projects.

[Paraview] "Plot Data" filter has problem with negative values

[FERHAT HAMIDA Abdelhak via ParaView]

I want to plot a tabulated fonction (say F=cos(t)) using paraview which reads 
the values of t and F from a csv file then the plot F-t is generated by the 
"Plot Data" filter. t takes values in the [-1,+1] range.The problem is:
   - "Left Range Axis Maximum" can hold negative and positive values.
   - "Left Range Axis Minimum" can not hold only negative values or zero.
Thi results in: negative values of the function are not plotted.The only 
solution I found is to get a plot of the reverse function (-F) by setting "Left 
Range Axis Maximum" to a (-1) and "Left Range Axis Minimum" to (+1) which is 
very strange (Maximum < Minimum). The csv data and the plot are in the attached 
files.  
So please is there a solution to this problem or is this a bug in 
paraview?Nota: I get this with paraview 4.4.0 and 5.2 versions on Centos 7.

Re: [Paraview] Plot over time at an xyz location

[Andy Bauer]

Hi Alan,

How about using the Extract Location filter using the interpolate at point
for the mode and then do a Plot Selection Over Time after selecting that
point?

Thanks for asking the question -- I didn't know about the Extract Location
filter until I tried answering this! I was originally thinking of using a
Point Source at the desired location and then Resample with Dataset filter
before doing the Plot Selection Over Time. I'm sick of Ken Moreland always
coming up with better ways of doing what I suggest on the mailing list for
questions like these so this time I looked into it a bit more :)

Cheers,
Andy

[Paraview] Plot over time at an xyz location

[Scott, W Alan]

Is it possible to plot some variable over time at an xyz location?  For 
instance, if I have water flowing down a pipe, and want to plot the pressure as 
the water velocity increases one unit (i.e., cm) in from the edge of the pipe, 
how do I do it?

Thanks,

Alan

[Paraview] Plot csv over time

[Jamison, Ryan Dale]

Hello,

I was wondering if there is a way to plot csv data over time? Specifically, I 
would like to read into an active Paraview session that already has some exodus 
results loaded a csv file (this I can already do). This csv file came from the 
same simulation as the exodus data. I’d like to then plot the csv results over 
time such that the green vertical line shows up denoting time as a video plays. 

I’ve found I can use “plot data” for the csv data and I can indeed plot time 
vs. variable but the green vertical line doesn’t appear. My theory is that the 
vertical time marker only appears when plotting something over time with the 
appropriate filter. Any idea how to get the time marker to appear in the plot? 

Thanks, Ryan Jamison

[Paraview] Plot time in a Line chart view

[no name]

i want to pick up this problem:

http://www.paraview.org/pipermail/paraview/2011-April/021225.html

I have a rather simple quest: I have a line chart view, that shows
various plots, and I want to show when time goes on see where I am
(Plot is Energy over time). So for example I want a black line, that
goes vertically with the time over my linechartview.

I can get the time with
inputs[0].GetInformation().Get(vtk.vtkDataObject.DATA_TIME_STEP())

But I don't find a cheap way to display it in the line chart view.
Sadly, the plot time filter only works in the quartile view and also
it is not made for my problem :(

Thanks!

Re: [Paraview] plot min/max/average of a variable in all cells/point of a block over time?

[Dennis Conklin]

Alan,

Couldn't you just select the block, then use Plot Selection Over Time with 
"Only Report Selection Statistics" selected, without actually extracting each 
block?

Re: [Paraview] plot min/max/average of a variable in all cells/point of a block over time?

[Moreland, Kenneth]

This is way harder than it should be, but it is working in 5.0:

1. Select the block you want the plot for. You can over the mouse over the 
block and hit the b key.
2. Run the "Extract Selection" filter on that block.
3. Open the Find Data dialog.
4. In the first line, choose points or cells (depending on what you want to 
plot), and "ExtractSelection#".
5. In the first criterium line, select "ID" "is >=" "0"
6. Click "Run Selection Query"
7. Click "Plot Selection Over Time"
8. Apply the filter that is created.

The resulting plot will show the min, max, average, and quartiles of all the 
variables. Select down to the one you want to see.

-Ken

Is there a method to plot the min/max/average value of a variable in a block(s)

[Paraview] Plot on sorted lines with Cell Array

[Christophe Bourcier]

Dear Paraview users,

I want to plot a field on cells with the same discretization as my
mesh. So I don't use Plot over line, but Plot on sorted lines with 2
slices to get the polyline to plot data on.

It works well with a field on nodes, but I can't get a result with a
field on cell. Of course if I use Cell data point data, I get a plot,
but with mean values on the nodes.

In Plot on sorted lines properties, if I choose Attribute type Cell
data, I can't see my field on cells in the list of available fields.

To reproduce the issue:
- download the dataset (802K) : http://bourcier.eu/secteur.tgz
- open it
- display the field U2
- apply a slice in Z normal
- apply a slice in Y normal
- apply Plot on sorted lines
- change Attribute type to Cell data: the field U2 is not available.
- apply the filter Cell data to point data (with Pass Cell Data
ticked) before Plot on sorted lines
- in Point Data, U2 is available, but the resulting plot has mean
values on nodes between cells that have not the same value on the left
and on the right. Zoom at the right end of the line to see it.
- in Cell Data, U2 is now also available, but nothing is displayed. I
would have expected to see a stairstep graph.

Have you an idea on how to get this?

Thank you.

Christophe

Re: [Paraview] 'Plot Data' missing Points X/Y/Z as option for X axis on 5.0-RC?

[Joachim Pouderoux]

Giuseppe,

You are right. I think this is something we should have addressed with
https://gitlab.kitware.com/paraview/paraview/merge_requests/385

So I have just made a patch for this:
https://gitlab.kitware.com/paraview/paraview/merge_requests/515
If it is all OK it should be ready for 5.0RC2 (at worst for 5.0 final).

Best,

[Paraview] 'Plot Data' missing Points X/Y/Z as option for X axis on 5.0-RC?

[Giuseppe Bilotta]

Hello,

up until 4.4 I could use the Plot Data filter to plot any quantity
over any spatial coordinate for the points. I would Pick "Points (0)"
or "Points (1)" or "Points (2)" as X Array Name (after un-checking
"Use index") and select any array I wanted to plot in the Series
parameters.

In 5.0-RC this doesn't seem to be possible anymore: I have Points X,
Points Y and Points Z as options for the Series, but not for the X
Array. There is a horrible workaround to plot a single array (pick the
array as X and the Points X as Series), but it's a hack and it can't
be use for multiple series.

Suggestions?

Re: [Paraview] plot title

[Samuel Key]

Aleksejs,

This is not the only way, but a convenient way to add a title to an 
animation.


Add an Annotate Time filter to the pipe line. Hit apply. Make sure that 
'gear' button is slected. There are 6 'default' locations: Top-Left, 
Top-Center, Top-Right, Btm-Left,... Also, you can pick a custom 
location. Text font and size is completely selectable.


You can either use "Time: %f" and add title text after it, before it, or 
erase "Time:%f"


You can add in parallel another Annotate Time filter... und so weiter.

Hope this helps

Hey Samuel,

This really helps. To be honest, I knew about the annotate time feature, but I 
thought I could have time in the lower corner and title on the top. Anyway, 
this works as well

Thank you

Re: [Paraview] Plot Cell ID over time

[Moreland, Kenneth]

Macro,

I'm not entirely sure what you are expecting to happen when you select a
column and as ParaView to plot it over time. ParaView will take statistics
over the id values and give you a quartile plot on that. I don't think
that is what you want. From the earlier part of your email, it sounds like
you really want to plot the number of cells over time. To do that, you
first need to compute the cell count into some sort of data structure.
Unfortunately there is no direct way to do this, but I found an old email
thread 
(http://www.paraview.org/pipermail/paraview/2008-November/010080.html)
that describes how to leverage the histogram filter to do it. Here are
some updated instructions for ParaView 4.4.

1. Run your data through the Histogram filter. Set "Bin Count" to 1. Make
"Select Input Array" point to a cell variable. Apply. The result should be
a histogram with exactly one bin.

2. View the data in the Spreadsheet view. Close all the views and then
select "Spreadsheet View" in the resulting empty view. Make sure the
Histogram filter is visible in the spreadsheet view. There should be a
single row. Select that row so that it is highlighted. (Note, this is only
necessary because issue 14978 is not implemented yet.
http://www.paraview.org/Bug/view.php?id=14978)

3. Add the Plot Selection Over Time filter. Apply.

[Paraview] Plot Cell ID over time

[Marco Kokic]

Dear paraviewers,

I am analyzing 2D tissue data and I would like to count the number of 
cells over time. After I extract a polygonal mesh from my multiblock 
dataset I want to visualize the polygonal mesh statistics which show the 
number of cells at every time point. Unfortunately, I cannot find a way 
to plot the selected Cell ID column over time (see screenshot here: 
http://imgur.com/LICqYdV ). Any suggestions on how to get around this?


Thanks in advance !

Re: [Paraview] Plot Cell ID over time

[Moreland, Kenneth]

Macro,

That does seem like a better way to go about it. I think you can shorten
your steps by about half. Try these steps. The first 3 are the exact same
as you describe.

1. Edit -> Find Data.

2. Find Cells where ID is >= 0 (and any other selection criteria). "Run
Selection Query"

3. "Plot Selection Over Time." "Apply"

4. In the resulting plot view, edit the Series Parameters to turn off all
variables except "N".

Re: [Paraview] Plot Cell ID over time

[Marco Kokic]

Hello,

thanks for your answer. Unfortunately, there is no cell variable. So I 
can't point "Select Input Array" to anything useful. I found another 
difficult way though to achieve my goal: First I select the Last Frame, 
then Edit -> Find Data, there I choose "Find Cell(s) from Extract 
Block", "ID is >=0", "Block ID is 1", "Run Selection Query" and then 
"Plot Selection Over Time". If I then open the Spreadsheet View, I find 
a dataset containing (among other columns) the number of cells N and the 
Time. If I the toggle all unnecessary columns, select all entries in my 
two columns and then Filters -> Data Analysis -> Plot Data, I finally am 
close to what I wanted to visualize. If anyone knows a less laborious 
way, please let me know. Thanks in advance.


Best regards,
Marco

Re: [Paraview] Plot over Line source

[no name]

Hey Cory

Thanks for the tip with the array [(0,0,0)  (0,0,0),
(x,y,time),(0,0,0)...(0,0,0)] While this was easy to do, I still get a
point in Paraview at 0/0 for each time, or, if I choose to draw a line, one
that starts at 0/0 - which is kind of understandable, when looking at my
table, which is 0 everywhere but on one point. Can you give me another hint
on how to proceed? I only want PV to draw ONE point at (x,y)...

Thanks

Richard,

I understand. Sorry, I don't think there is a way to do this.

Having an annotation mechanism for your use case might be something we can
do in the future, but there are currently no plans to do this that I know
of.

Hi Richard,

Please keep your replies on the list with a "reply-all". Someone else may
have a similar question as you (or better yet, an answer) and this may come
in handy in a future search of the list serve.

I'm not sure how to annotate the position on the graph as you seek to do as
there is no mechanism for this. You could perhaps hack this in by creating
another column in your table where all the values are zero except for the
time that you are showing. Setting this column to the maximum of your
plotted y values in the row at the time you are showing would result in an
almost vertical line showing up at the time you are displaying if your data
samples in x are dense enough.

HTH,
Cory

 One last question: Line Chart != PlotOverLine, so its hard for me to
 plot x and y axis, or like in my script mx over hx, as nothing happens when
 I choose to use one of my coordinates as "X-Axis Parameter" and just let
 the other one being drawn.

 Can't I make a real Plot over Line?

 Thanks again for your time!

 Thanks for the hint! I did some coding and I got stuck at the vtkTable
 as Output DataSet Type.


 I used -> Programmable Source and then vtkTable which gives me the

 for the code I am using:

 class DataFile(object):

Re: [Paraview] Plot over Line source

[Cory Quammen]

Hi Richard,

If you don't mind, let's keep the discussion on the list so that others may
benefit from the discussion.

Outputting a vtkTable is the right thing to do. What I suspect is happening
with the first error message is that if you execute a programmable source
with the output set to one type of data set (e.g., vtkPolyData), there is a
bug that doesn't let you switch to a different type of output. As a
workaround, you can create a new Programmable Source, copy and paste your
code from the original Programmable Source into the new one, and set the
output type to vtkTableData *before* you click Apply.

To view line plots of your data, you'll need to create a Line Chart View by
splitting the 3D Render View. To do this, look for the icon on the top
right of the 3D Render View that has two vertically-oriented rectangles
side by side (tool tip "Split Horizontal"). In the list of views that comes
up, click on "Line Chart View". If your line plots are not visible right
away, you will need to make them visible by clicking on the eye icon next
to the Programmable Source. Voila, you should have a line plot.

Hope that helps,
Cory

[Paraview] Plot over Line source

[no name]

Hey there

I have some hundred VTU files and I want to plot some data in a graph (Plot
over Line - POL) next to it. The Problem is, the data from these POLs is
coming from a simple log file, basically conaining only x and y values
(like two np.arrays).

I can transform the arrays via

from vtk.util import numpy_support
values = np.array((x,y))
vtk_values = numpy_support.numpy_to_vtk(values, array_type=vtk.VTK_FLOAT)
vtk_values.setName('values_2_show')
vtk_values.setComponentName(1, 'x_value')
vtk_values.setComponentName(2, 'y_value')

But so far I have no success with how to change the input (source)

VTUFILE = FindSource('VTUFILE*')
plotOverLine1 = PlotOverLine(Input=VTUFILE, Source='High Resolution
Line Source')

to a simple array.

Thanks for any help!
Richard

Re: [Paraview] Plot over Line source

[Cory Quammen]

Hi Richard,

You won't be able to set a vtkDataArray subclass as the input to a
PlotOverLine filter. Instead, you should read the log files in a
Programmable Source, and connect the Programmable Source to the
PlotOverLine filter.

See Chapter 13 of the ParaView Guide [1].

Hope that helps,
Cory

Re: [Paraview] Plot cumulative integral over time of a variable

[Andy Bauer]

Hi Alan,

For #2, a hacky way would be to use the temporal statistics to get the
average value and then multiply that by the number of time steps. The only
other way I can think of is by using a Python Programmable Filter to
integrate the values over time. The Python Programmable Filter recently was
changed to have access to the pipeline executive so that you can have it
iterate over time steps.

Attached is a state file which I used to iterate over time steps in a
programmable filter. It's not working with PV 4.3.1 but it may help give
you some guidance on how to do it. If it's overly confusing  (which it very
well could be -- I'm too lazy to look at it closely right now) let me know
and I can see if I can update it to work with the latest version of PV.

Best,
Andy

Re: [Paraview] Plot cumulative integral over time of a variable

[Utkarsh Ayachit]

Alan,

Attached is a state file (using can.ex2) which indeed uses numpy.trapz() to
do the work. It needs a small patch to be applied to VTK (attached) to
avoid a segfault.

The Programmable Filter adds a new row-data array named trapz which is
the result of the operation (it's repeated so we can add it to RowData
rather than field data.

I am correct that your dataset is just a point-cloud or am I missing

 Make sure you have Compute Scalars option checked on the

Re: [Paraview] plot contour in ParaView

[Yifei]

Thanks for your reply. My goal is to plot stress contour for my simulation 
results. It seems to me that when I use pizza.py to convert dump file from 
LAMMPS into other file types, the data is always point data (coordinate and 
value at a point). So I wonder if I could convert the dump file into certain 
file types ParaView could use to plot contours?

As far as I know, in MATLAB I could use griddata function to interpolate 
scattered data (point data in 2D). Then use contourf function to generate 
contours. I wonder if ParaView provides similar functions like griddata to 
convert the input data, then apply the contour filter?

Thanks,
Yifei

[Paraview] plot contour in ParaView

[Yifei]

Hi,

I am trying to post-processing my simulation results from LAMMPS using 
ParaView. I first converted dump file into ensight file format using pizza.py. 
The script is attached behind. 

import sys
from dump import dump
from ensight import ensight
d=dump(dump.peri);
d.map(1,id,2,type,3,x,4,y,5,z,6,damage,7,vx,8,vy,9,vz);
e=ensight(d);
e.one(disk,damage,Damage,y,Position_y,x,Position_x,z,Postion_z,vy,VY,vx,VX,vz,VZ”)

Then, I imported the .case file into ParaView. Now I have the coordinate, 
damage scalar, and velocity components for each point. I wonder how can I use 
the Contour filter in ParaView to plot contours? When I try to do that, I got 
only one coloring option called Solid Color. How can I use damage or velocity 
as the coloring options?

Thanks,
Yifei

Re: [Paraview] Plot 3D Function names

Unfortunately, there is not a super easy way to rename an array. You have
to use the Programmable Filter with something like this:

from vtk.numpy_interface import dataset_adapter as dsa
itr = dsa.MultiCompositeDataIterator([inputs[0], output])
for inp, opt in itr:
opt.PointData.append(inp.PointData['function1'], my function)

[Paraview] Plot calculator result over time

[Dalla Piazza Thomas]

Hi all,
I have a simple problem that is easy to reproduce. My objective is to 
produce a plot of average temperature of a volume over time (simple heat 
diffusion case). I'll take a straight forward example based on 
laplacianfoam OpenFOAM case.


1) Run the case
2) Run Paraview and load the data for internalMesh region
3) select filter Integrate variables that produce integrated 
temperature over the entire volume (Tv in the following) and integrated 
volume over volume being the total region volume (Volume in the following)

4) select filter Calculator
5) based on cell data, compute averaged temperature of the volume 
Tv/Volume (both results of integration filter)

6) select calculator result and choose filter Plot selection over time

Problem: Up to the calculator, everything looks fine. Integrated volume 
is not changing over time, itegrated temperature is growing normally as 
well as averaged temperature... But in the spreadsheet view of Plot 
selection over time, only the initial value at T=0 is right, for the 
next time steps, volume is changing like randomly and averaged 
temperature is completely messed up...


Is it a bug of PlotSelectionOverTime filter or did I made a mistake in 
my procedure?


Thanks for any help,

 Thomas

Re: [Paraview] Plot point variable over time

[Utkarsh Ayachit]

Rakesh,

The dataset you included doesn't have any timesteps. Nor I do I see
any variable named displacement. The only variables available are
uvw. To plot over time, you select the cells or point that you want
plot over time and the create the Plot Over Time filter. That would
show you a plot of the attributes for the selected elements over time.

[Paraview] Plot smooth particle data

[Timothy Charles Fagan]

Dear Paraview Community,

I have a set of particle data (.vtk polydata) that I would like to use for
a plot over a line. However I get a choppy line at best, and often very
large gaps in data.

I have tried applying the a 2D glyph and that works better, but is still
choppy. Also the Plot Data to Cell Data filter doesn't seem to help, though
I assume having cell data would create a smooth line.

I can get a better curve using the extract selection and plot data
function, but this becomes too dependent on how I select the data and I
can't do it with much accuracy.

Thanks,
Tim

[Paraview] Plot overline: specify points coordinates in different reference frame

[Francois Beaubert]

Hi all, 

I would like to use the Plot Overline filter but be able to specify the Point1 
and Point2 coordinates in a different reference frame (not cartesian). 

Obviously it's not possible to do this in the GUI, but is it possible to obtain 
such feature with a programmable filter ? 

I'm looking for a way to specify the 2 points coordinates in a cylindrical 
reference frame with (r,theta,z) defined as: 
r = sqrt(coordsX^2+coordsY^2) 
theta = atan(coordsY/coordsX) 
z = coordsZ 

My knowledge in python scripting for Paraview is nonexistent but I've tried to 
build a minimalist Programmable filter to just mimic the Plot Overline filter 
but was not able to make it work (see below). 

1. First step for me is to be able to build a Programmable filter that can do 
the same task as the Plot Overline filter. 
2. The next one will be to specify the (x,y,z) coordinates of the 2 points of 
the line given two (r,theta,z) cylindrical coordinates with: 
x = r*cos(theta) 
y = r*sin(theta) 

Any help will be warmly welcome :) 
Thank you very much. 

Francois 

 Programmable filter start here - 

from paraview.simple import Show 
from paraview.simple import PlotOverLine 
from paraview.simple import GetActiveSource 
from paraview.simple import CreateXYPlotView 


data = GetActiveSource() 


PlotOverLine1 = PlotOverLine( Source=High Resolution Line Source ) 


PlotOverLine1.Source.Point1 = [0.0, 0.0, 0.0] 
PlotOverLine1.Source.Point2 = [0.0, 0.1, 0.0] 

XYChartView1 = CreateXYPlotView() 


DataRepresentation1 = Show() 
DataRepresentation1.XArrayName = 'arc_length' 
DataRepresentation1.SeriesVisibility = ['Velocity (2)', '1'] 
DataRepresentation1.UseIndexForXAxis = 0 


 Programmable filter stop here -

Re: [Paraview] plot HDF5 with time using XDMF

[Jason Fleming]

Hello Ramiz

I believe you need to create a GridCollection, and set the CollectionType
Attribute to Temporal. Then give each Grid in the Collection the
appropriate Time attribute. I've attached the output from one of the
example programs included in the XDMF2 repository that illustrates this.

Cheers

[Paraview] plot HDF5 with time using XDMF

[ramiz . azadaliyev]

Hello everyone, 

 I am new to ParaView, and so far I was able to use it without much 
trouble. 
But I have hit a dead end, I have looked online for example, but 
unfortunately it did not help me.
I have managed to create XMF file that gives me a 3d plot, but I can't 
figure out how to couple the time data with the coordinates. 

MY GOAL IS TO BE ABLE TO PLOT THE DATA CHRONOLOGICALLY

the HDF5 file has 3 datasets for X Y Z, 1 for amplitude, and 1 for time. 
All are of the same hierarchy. 

Use the following code: 
?xml version=1.0 ?
!DOCTYPE Xdmf SYSTEM Xdmf.dtd []
Xdmf Version=2.0
 Domain
 
Grid Name=mesh3 GridType=Uniform 
 Topology TopologyType=Polyvertex Dimensions=4 /

[Paraview] plot 2D integral of 3D scalar field

[korolkovas]

 Hello,
I can't seem to figure out whether this is possible with Paraview... My
data consists of a scalar field localized in one region of space,
representing a density. I want to compute and plot the 2D integral of
this density to obtain in the form of a curve, i.e. the density along
the z-axis would be:
int2d [rho(x,y,z) dx dy]
Also, can I compute the moments of my distribution, for instance Rx^2 =
int3d (rho*x^2) ?
Thanks,
Airidas

[Paraview] Plot over line

[Colin McAuliffe]

Hello all, I would like to use a plot over line filter where the line  
is defined by two nodes on the mesh, which move in time, rather than  
defining the line with two fixed spacial points. Is it possible to do  
this with the POL filter as is, or will this require some extra  
scripting?


Thanks
Colin

Re: [Paraview] Plot over line

[Samuel Key]

Colin,

A not necessarily straight forward way is to use the Warp filter to 
remove the mesh motion (assumes you have the displacement vector as a 
point value in your datum set). Then the POL Filter end-points remain 
fixed with respect to the two nodes over which you initially placed the 
end-points.


However, implicit in this approach is that the POL Filter's line is a 
material line and deforms with the material, probably not remaining a 
straight line as the time (or loading) progresses. It may or may not be 
the result for which you are looking?

Re: [Paraview] Plot over line

[Colin McAuliffe]

Hi Samuel, thanks for the response. My line is on a boundary which  
remains a strait line so there is no worry of the line becoming  
curved. My data set contains mesh node points which are fixed in time,  
along with the nodal displacements which give the deformed  
configuration when the warp filter is applied. I can do what you  
describe but this will give me the POL of the undeformed  
configuration. What I want to do here is get a plot over line on the  
warped mesh, since I need to compute an integral along the warped edge.


Thanks
Colin

Quoting Samuel Key samuel...@bresnan.net:

[Paraview] Plot selection over time

[Hedieh Ebrahimi]

Hello all,

I have a question. Is there anyway to draw the result of a filter over time.
I have a programmable filter which is giving back one number for each time
step and I like to draw this over time, but the plot selection over time
will not do this for me.

I know I can use Excel of course, but is there anyway to pass an array
which is the result of the  filter just before the Plot Selection Over
Time on data set to it and then draw this using paraview?

I mean having filters in order of following:

1.Dataset
3. Python Calculator
4.Plot Selection Over Time

Any idea how to do this?

I have a 3D dataset with 500 time planes.  I want to use Plot Over Line to show 
a variable but averaged over, say, the last 100 time planes.  Is this possible?

Re: [Paraview] Plot over line, averaged over time.

[Utkarsh Ayachit]

Temporal Statistics -- Plot Over Line should do the trick,
however, for the entire 500 timesteps. We don't have an easy mechanism
to limit it to last 100 timesteps. However, it's just a matter of
writing a filter to do that (similar to Temporal Shift Scale).

Sure:
1. Apply Integrate Variables. Select the single cell (or point) from
the spreadsheet view showing the selection
2. Now apply Plot Selection Over Time

Re: [Paraview] Plot probe value over time

[Zenker, Dr. Matthias]

Hi Utkarsh,

I'm afraid I don't understand what you mean. The string select points does 
not figure in the User's Guide. AFAIK I can select a point only if it is a 
node. But I would like to probe the temperature at a point which is located 
between nodes, so I need to interpolate. The interpolated temperature should be 
plotted over time.
So my question: How do I do that?

Thank you for a further explanation,

Matthias

Re: [Paraview] Plot probe value over time

[David E DeMarle]

The simplest way to do what you want is to use the Probe Location
filter to specify the point in space you want to sample values onto,
then use Select Points On to make a selection of that filter's
output. Finally apply Plot Selection over Time.

  The simplest way to do what you want is to use the Probe Location
  filter to specify the point in space you want to sample values onto,
  then use Select Points On to make a selection of that filter's
  output. Finally apply Plot Selection over Time.

   Hi Utkarsh,
  
  
  
   I'm afraid I don't understand what you mean. The string select

   temperature at a point which is located between nodes, so I need to
 interpolate.
   The interpolated temperature should be plotted over time.
  
   So my question: How do I do that?

[Paraview] Plot probe value over time

[Zenker, Dr. Matthias]

Hi,

I would like to plot a value (say, the temperature) at a specific point 
(coordinates) over time. If there is a node at that point, I can use the Plot 
Selection over Time Filter. If not, it should be possible to use interpolation. 
I can use the Probe Location Filter to define a point by its coordinates. But 
how do I plot the temperature over time at that point? I didn't manage to do 
that so far, and would be grateful for a helpful hint.

Thanks,

Re: [Paraview] plot 2d curve

[Utkarsh Ayachit]

By argument, you mean as an input dataset? You'll have to create a
vtk-dataset (vtkTable) using the array. I believe there are examples
on the Wiki how to do that. Let me know if you cannot find them, and I
can fish them out for you.

 If you're using Python scripting exclusively, then you can indeed
 directly use matplotlib or any other Pyhton modules for generating
 plots. However if you want those plots to be rendered in the ParaView
 GUI or on tile-displays, etc. then you want to use ParaView's plots.
 For that can use the Calculator or Python Calculator to compute the
 derived quantity then apply the Plot Data filter to plot the arrays
 in plots.

Re: [Paraview] plot selection over time

Suppose I want to plot a cell variable as a function of time. I can see how to 
do that with the PlotSelectionOverTime filter. But what I really want to do is 
the same plot for many cells, all at the same time. Is there an easy way to do 
that? On the Display tab, PlotSelectionOverTime only allows me to select one 
cell at a time.

Re: [Paraview] Plot over line CSV export python script not working

[Luca Giannelli]

Thank you very much Andy,
with your precious help I have been able to find out a working solution for
what I need.

I foud out the the original script is completly functional without any
modification
the only BIG ISSUE was the the Paraview binaries provided by the Ubuntu
Repositories
do not provide all the needed python scripts for the execution of a perfect
python environment
in Paraview. I would like to notify this to the mantainers of the repos.
So, the workaround was this easy! I just installed Paraview from the latest
source and got
the thing running.

However I found another problem relatet of course to the execution of the
pipeline due to
the missing active source, just as you suggested in you mail. That was
easier to solve.
So I ended up with a working script I want to share with all those people
that may need it.
I'll send an heavily commented version with a dedicated email. Here is a
snippet just to let you
see how i did.
Thank you very much for your time!

Luca

-- CODE---

try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

fotobioreattore_foam = FindSource(fotobioreattore.foam)
SetActiveSource(fotobioreattore_foam)

PlotOverLine2 = PlotOverLine( Source=High Resolution Line Source )
DataRepresentation7 = Show()

PlotOverLine2.Source.Point1 = [0.0, 0.0, 0.0]
PlotOverLine2.Source.Point2 = [0.0, 0.0, 0.43]

Render()

source = PlotOverLine2
writer = CreateWriter(YOUR_FILE_NAME_GOES_HERE.csv, source)
writer.FieldAssociation = Points # or Cells
writer.UpdatePipeline()
del writer

---

2011/9/30 Andy Bauer andy.ba...@kitware.com

 I think the first problem is that there isn't an active source.  The
 GetActiveSource() is returning None and when you create subsequent filters
 that automatically connect to the active source it causes problems when you
 try to execute the pipeline.  Something along the lines of below should get
 you closer:
 =

 try: paraview.simple
 except: from paraview.simple import *
 paraview.simple._DisableFirstRenderCameraReset()

 Wavelet()
 p = PlotOverLine()
 p.Source.Point1 = [-.5, -5., -5.]
 p.Source.Point2 = [.5, 5., 5.]
 w = CSVWriter()
 w.FileName = /home/piota/csv.csv
 w.UpdatePipeline()
 =

 The problem here is that the output of PlotOverLine is a polydata and the
 writer is expecting a vtkTable.  I'm not sure how to convert between the
 two.  Maybe someone else can help you with that.

 The 2 things I'd try at this point are either creating my own writer using
 the python programmable filter or writing out a polydata file and parsing
 that for the information that you need.  The first one is probably the
 better choice of the two.

 It looks like a complain about the server, not about my script though
 in fact, if comment out the writer part, leaving only the trace recorded
 set of operations, it spits out the very same error. Moreover, the Paraview
 output doesn't show any output at all (except for the usual a complain about
 the qt4 that is not related).

 Do you see any evident problem in the script syntax in the writer section?
 For example references to the wrong source, etc?

 Or do you believe that it is a problem related to the Paraview/Python
 installation (or whatever..).


 Another point does the PlotOverLine2 influence the results? I
 recorded the 

[Paraview] Plot over line CSV export python script not working

[Luca Giannelli]

Hello everybody,

I've been using Paraview for quite a long time but I didn't need the python
scripting up to now.
I want to execute a series of plot over line in numerous points and
different time steps so it is nothing
I can afford to do manually.
Looking on the net I was able to find out how to record a macro and how to
create a writer so I
ended up with this script:


try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()

fotobioreattore_foam = GetActiveSource()
PlotOverLine2 = PlotOverLine( Source=High Resolution Line Source )

PlotOverLine2.Source.Point1 = [-0.03511841783524, -0.03509980067610741,
0.0]
PlotOverLine2.Source.Point2 = [0.03511841783524, 0.03511841783524,
0.430071525574]

DataRepresentation7 = Show()

PlotOverLine2.Source.Point1 = [-0.0, 0.0, 0.0]
PlotOverLine2.Source.Point2 = [0.0, 0.0, 0.430071525574]

XYChartView4 = GetRenderView()
DataRepresentation7.XArrayName = 'arc_length'
DataRepresentation7.SeriesVisibility = ['U (0)', '0', 'U (1)', '0', 'U (2)',
'0', 'vtkValidPointMask', '0', 'arc_length', '0', 'Points (0)', '0', 'Points
(1)', '0', 'Points (2)', '0', 'Points (Magnitude)', '0']
DataRepresentation7.UseIndexForXAxis = 0

Render()

#= create writer
source = PlotOverLine2 #PlotOverLine2.Source
writer = CreateWriter(/home/piota/csv.csv, source)
#writer = CreateWriter(/home/piota/csv.csv)
writer.FieldAssociation = Points # or Cells
writer.UpdatePipeline()
del writer
--

If I'm not mistaken, this should write a csv.csv file in my home folder but
it doesn't write anything. No error is reported when I run the script but
still I get no output.
I'm still a bit confused on which source I should specify, so I'm pretty
sure that the writer part is incorrect.

Can somebody help me filling it out properly?

Thx in advance.

 If you're running the python script in the paraview gui sometimes the
 messages are printed out to the python shell.  What version of paraview are
 you using?

 I'm running paraview from the head of the repo.  The output I get from the
 OutputMessages window is:

Re: [Paraview] Plot over line CSV export python script not working

[Luca Giannelli]

Ok,

I moved on a little. Reading the output of the error reported in the
previous mail, it says that it cannot find XArrayName. Looking the
original script you can see that it is needed for the definition of the plot
area properties in the GUI I don't need it as I only want a csv file, so
I commented out everything in that section. Running the script again it now
complains about being unable to find CreateWriter. I need this to write
the csv file so this error becomes fatal.
As this function should be included in the paraview.simple that I load at
the beginning of the script (like explained in the manual), what I did was
to go through all the functions in the simple.py file to locate it. Without
any succes. Then I went on with the brute-force approach and lauched:

grep -H -r CreateWriter /usr

Binary file /usr/lib/paraview/libvtkPVFilters.so matches

Binary file /usr/lib/paraview/libvtkPVServerManager.so matches

Binary file /usr/lib/paraview/libvtkIO.so.pv3.8 matches

Binary file /usr/lib/paraview/libvtkPVServerManagerPythonD.so matches

Binary file /usr/lib/paraview/libpqApplicationComponents.so matches

Binary file /usr/lib/paraview/libvtkIO.so matches


Unfortunately they are all bin files and not py...

I'm starting to believe that I'm really missing something here.

Any idea?


Thx!!!

 Andy,

 thank you for your quick reply.

 I am using Paraview 3.8.0 which is the latest binary in the Ubuntu repos. I
 chose to install that without compiling from source as I was rushing (I
 know, it sounds weird... but). Do you believe that the problem is
 build-related?

 However, reading the errors that you get I don't see anything that I can
 visualize in my output which is as follows (Python shell)

[Paraview] Plot Maximum Value over Time

[Jeffrey Martin]

Hi, I was wondering if you could give me some advice:

I extracted some points from a clip plane with the extract data selection 
feature 
and we want to plot the maximum value (speed in this case) of these points over 
time.  

The extract data selection filter shows the upper and lower bounds, but we just 
need a way to plot the upper bound (i.e. maximum) over time.  I've looked 
online 
at spreadsheet view, but can't seem to get a definite answer.  Do you know how 
to do this?

Thank you

Re: [Paraview] Plot Maximum Value over Time

[Moreland, Kenneth]

The following is inelegant, but should work.  First, run the Descriptive
Statistics filter on whatever data you want to plot the maximum.  From
your description, it sounds like it would be the output of an extract
selection filter.  In the object inspector, select only the variable you
are interested in (in your case speed).

The descriptive statistics filter has two outputs, the Statistical Model
and the Assessed Data. You are interested in the Statistical Model.
When you apply the descriptive statistics filter, ParaView will add two
spreadsheet views, one if which is showing the statistical model.  It
should show a table with one row that describes the name of your variable
and the statistics computed from it (maximum being one of them).  Click
that row to select it.

With that row selected, create a Plot Selection Over Time filter.  In
the resulting plot, turn off all series except Maximum.

Note that in the future we hope to integrate these descriptive statistics
with the Find Data dialog so that you can just directly select the
maximum value and plot that selection.

Re: [Paraview] Plot field data over time?

[Utkarsh Ayachit]

Eric,

If I remember correctly, this filter is designed to work with
ExodusIIReader alone. Exodus puts what it calls Global Variables in
the FieldData, and this filter is generating a plot for that. It
shouldn't be too hard to create a Plot FieldData Over Time filter
modeled on vtkExtractArraysOverTime.

 Am I misunderstanding the use/point of this filter?
