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".

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

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.

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

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 !
With best regards,
Marco
