[Matplotlib-users] two axes on top of one another with one rotated
Sorry if this ultimately goes through more than once. I am having some issues with submitting it I need to teach coordinate systems and transformations to a college robotics class. I have used Tikz in the past to generate some graphics, but I want to switch to doing everything in matplotlib if possible. (Tikz is super powerful and makes beautiful graphics, but it always takes me a long time to generate a figure). One of my initial problems is drawing two axes on top of one another, but with one of them rotated by an arbitrary angle. I am attaching the Tikz result that I want to recreate in matplotlib. Other than drawing lines "by hand", I don't really know where to start. Any help would be appreciated. In case the mailing list doesn't allow attached graphics, here is a link to the image on my google drive: https://drive.google.com/open?id=1XVKcZEK76SQL2cW5yASbQCMvR0GZKgz- Thanks!

Re: [Matplotlib-users] show() blocks script execution for TkAgg from ipython -pylab
0.99.3 is more or less fine, but there is an annoying exception window that pops up if you close IPython with a plot window open (using the TkAgg backend). But in my mind this is less bothersome than having to close all the plot windows every time I run a script (I tend to write scripts that generate 5-10 plots at a minimum). If I could easily build an installer from svn, I would try it. I don't have any microsoft compilers installed on my windows computers.

Re: [Matplotlib-users] saving a PNg jsut as dispalyed
I guess you could read the rcParams value that corresponds to the screen display and set rcParams['savefig.dpi'] to that value (this might work): mydpi = rcParams['figure.dpi'] rcParams['savefig.dpi'] = mydpi But that seems slightly hackish and maybe not much more elegant than what you are currently doing with passing dpi into savefig.

I think all that does is set the default dpi for savefig. I don't want any default, I want it to use the same dpi that is being used for display, and I don't know ahead of time what that is, I expect it is system dependent. Or do you mean that if I comment out that line, it will default to the one already in use? In which case, I need to go figure out how to change that in code, rather than messing with my matplotlibrc. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] - Check out the new SourceForge.net Marketplace.

This is all straightforward and clear. The one statement I've not yet
understood is this:
self.graph = matplotFrame3.PlotPanel(self.panel1 ,xpoints,
ypoints)
I assume that matplotFrame3 is the name of the module in which you've
written PlotPanel(). Is this assumption correct?
Exactly. That is the module which I mention importing in step 4.
I'm modifying your approach to suit our application but it seems to be
the
most parsimonious and elegant solution for simple display of plots in a
wxPython panel.
Thanks,
Glad it will help your application.

[Matplotlib-users] wxmpl: Can't create printer PDF because the id PDF is already used
I just created a small wxmpl example that I really like (attached),
but when I run it, I get these error messages:

I don't know if this is wxmpl specific, caused by wxPython, or caused
by matplotlib, but I would like to make it go away. Any thoughts?

[Matplotlib-users] zeros and ones difference between pylab and scipy
I have successfully (I think) coerced my students into using Scipy/Numpy for signal processing and dynamic system modeling. They are mechanical engineering coming from a Matlab background. In order to make using Python easy and have it feel like Matlab, I teach them to put from scipy import * from pylab import * at the beginning of every script. One problem with this is that the zeros and ones functions of pylab default to integers while those from scipy default to floating point numbers. I have had several students this week beating there heads against problems that turned out to be trying to put floating point values in an array that was created using pylab.zeros. Can this be changed? Is there a better approach I should take in getting my students started using scipy and pylab together? Thanks, Ryan - This SF.net email is sponsored by: Splunk Inc.

I realized that the ghostscript path wasn't set up properly, so that was
what was causing part of the problem with EPS files. It works sometimes
now (sometimes the EPS is just a blank file, even though the plot shows
up properly when I do pylab.show(). I'm still trying to narrow down
what ameks the difference here).
I guess I mean TeX-like mathtext format parsed by matplotlib. For
example, I'm using things like this:
rc('text', usetex=True)
Plotting.xlabel(r'\textbf{Time (s)}', fontsize=16)
usetex=True means that you are trying to use an external TeX program.
Ok, so am I to understand that usetex=True is not supported for PDF/EPS
output? Can you explain what the Tex-like mathtext format parsed by
matplotlib is?
Thank you for your assistance,

[Matplotlib-users] creating a timeline
I would need to create a timeline for a Latex document (eps output). There may be other tools besides Matplotlib and I am open to suggestions. But I were going to use mpl, what would it take to do something along these lines: http://www.timelinemaker.com/product-samplecharts-constructiontimeline.html Basically, I would need a nicely formatted dates along the x-axis and then lightly colored rectangles with text in them. The width would show when I anticipate some part of the project starting and ending. The y coordinate of the rectangle would used to allow project portions to overlap. It would be nice but not essential if the rectangles had a little fade in and out in their back ground color instead of a solid color, but that is not essential. Is there a clean way to do this with mpl? Thanks, Ryan - This SF.net email is sponsored by: Microsoft Defy all challenges.

See examples/broken_barh.py (this also allows breaks in the horizontal
bars, eg if an event is interrupted and then resumes). I haven't
added gradient fills on bars because I don't think they convey little
if any information but just add to the glitz factor (an example of
chart junk to use Tufte's phrase) but at some point we should bow to
popular pressure and add it. Actually, you can hack gradient filled
bars and axes backgrounds -- be careful, viewing the figure below may
induce seizures.

I am really just getting to mess with this now and ran into an issue.
I want to turn off the y axis and 3 sides of the border around the
plot area, so that I left with just the bottom x-axis and its tick
marks. Turning off the y axis is easy enough, but the only way I
found to get rid of the border is with
ax.set_frame_on(False)
which also gets rid of my bottom x axis and leaves tick marks along
the top (see attached). How do I get rid of the top tick marks, keep
the bottom ones, and get the bottom x-axis back?

I had tinkered with this a bit in the past and the final suggestion was to write some helper functions so that I could do the following: from mycyclers import colorcycler, linecycler for data in mydata: ax.plot(data, linestyle=linecycler(), color=colorcycler()) so that by writing a linecycler function I could control the line types plotted each time and the same with the color. Color would be specified as a grayscale such as '#808080' for a medium gray or '#00' for black. I didn't actually do it this way or I would post the code (I was in a hurry and did something hackish). I think that linecycler and colorcycler would be helper classes thta increment there own internal count when called and return a linestyle or color. I think what you want in the end is a simple way to do this: t=arange(0,1,0.01) y=sin(2*pi*t) x=cos(2*pi*t) plot(t,x,color='#00',linestyle='-') plot(t,y,color='#808080',linestyle=':') where color and line style would increment pseudo-automatically through lists you have defined and that you like.

What platform are you running? There should be an executable for
windows that puts them in the proper directory. They can go anywhere
on your PYTHONPATH, but the right answer is in the directory
C:\Python24\Lib\site-packages
(or I presume Python25 if you are running the current version of python).
So, I have the folders
C:\Python24\Lib\site-packages\matplotlib
C:\Python24\Lib\site-packages\scipy
etc.
On linux, you usually want to unzip the tarball and there should be a
setup.py file in the top level. Then just run
sudo python setup.py install
(or similar if you aren't on a debian based sudo distribution).
Let me know if you still have trouble.

[Matplotlib-users] subplots with the OO interface (ax.rowNum, ax.colNum)
I have a figure with 2 subplots (2 rows, 1 column) created using the OO interface like this: ax1=fig.add_subplot(2,1,1) ax2=fig.add_subplot(2,1,2) After I have created these axes and plotted things on them, I want to be able to set their x and y lims. The function that creates the plot returns fig. I can then get to a list of the axes from fig.axes. My question is this: can I know from the list of axes or their individual properties which one is which - i.e. which one is the top one and which one is the bottom one? It looks like ax1.rowNum and colNum should refer to the parameters I want (rowNum in this case, since there is only one column). But there isn't a docstring for them. Is this there intended use (or at least a safe use of them)? 99% of the time, I will create the top one first so topfig=fig.axes[0] and bottomfig=fig.axes[1]. But if I ever screw that up, it could be bad. Thanks, Ryan - Take Surveys. Earn Cash.

Re: [Matplotlib-users] pylab vs. embedding in wx
I am learning the hard way that I don't know as much about matplotlib as I thought I did except for how to use pylab. I think I have managed to create a figure, add an axis, and plot something on it without pylab, but I don't know how to do the equivalent of show(). draw() needs a renderder and I can't seem to figure out how to create one. Here is what I have done so far: myfig = pylab.Figure() myaxes=myfig.add_axes((0,1,0,1)) t=arange(0,1,0.01) y=sin(2*pi*t) myaxes.plot(t,y) What do I need to do to show the plot from the command line in IPython (i.e. if I actually want to use pylab instead of OO)? I may be going about this the wrong way and it may be easier just to set up some imports of pylab that only trigger inside of functions, but I would like to have functions that are useful either from the IPython command line or in OOP situations. Following the examples for WX, I am doing this at the top of my OOP modules: from matplotlib.backends.backend_wxagg import Toolbar, FigureCanvasWxAgg from matplotlib.figure import Figure . . . class mplpanel(wx.Panel): def __init__(self, parent): wx.Panel.__init__(self, parent, -1) self.fig = Figure((5,5), 75) self.canvas = FigureCanvasWxAgg(self, -1, self.fig) And the my drawing commands operate on self.fig and then the last line of all plotting functions is self.canvas.draw(). So, it would be nice if my utility functions took a figure instance as an input and operated on it. Am I making any sense? Am I going about this revision in a good way?

A good rule of thumb is to never import pylab at the top level for modules that need to be imported. In my own code, I often do something like def somefunc(figfunc): fig = figfunc() ax = fig.add_subplot(111) ax.plot([1,2,3]) and then I can call it with somefunc(pylab.figure) or a custom func that generates a GUI embedded figure instance. Eg, in my GTKApps, I have a functor like gtk_figure that returns a function that creates a figure embedded in a GTK window. In basemap, Jeffrey Whitaker does something like the following def somefunc(ax=None): if ax is None: import pylab ax = pylab.gca() Here the pylab import is triggered only when the function is called with default arguments. That way you can use it from GUI code without triggering a pylab import like somefunc(ax) and from other code where you want pylab do do everything with somefunc() I'm afraid you have some cleanup to do.

Re: [Matplotlib-users] pylab vs. embedding in wx
Thanks to Ken and John, I think I am off and running. Nice work on
wxmpl Ken! I think it fills a significant need.
The two attached files show a ridiculously simple example of what I am
planning to do. It may be completely obvoius to others. test_plot.py
is an example of a module that can be used from the command line with
pylab and IPython and it can also be imported into a WX app (as
demonstrated by wx_compatible.py). So, I will edit my data processing
scripts to use this approach.
Thanks again,
Ryan

Thanks for your thoughts Ken. Sorry, I assumed a bit on the context

mind and in all of them I have something like
from pylab import figure, cla, clf, plot, semiliogx, show, ...
at the top. This makes them completely incompatible with embedding in
a WX application. So, I need to re-write them and I want to know how
to do that best. John had some suggestions and I had some new
questions as I tried to act on his thoughts. So, the actual plotting
functions don't have to be re-useable in both contexts, but it would
be nice.
I can't actually run your code because I don't have the wxmpl.py
module. Looking at it, it looks like a really nice set of functions
that work cleanly with embedding in a backend. How could I call one
of the functions from the command line? Could I do something like:
import plotting, pylab
myfig = pylab.figure()
plotting.plot_simple(myfig)
and would I need any additional commands to actually show the figure?
Let me know if that makes sense and please send me the wxmpl.py file
or let me know where I can get it.
Thanks again,

Ryan,
In my (limited) experience, it's dicey to mix pylab's plotting
functionality and the OO API. I guess I'm a little unclear exactly
what your use case is for this. It sounds like you're goal is to
create a library of functions that operate on Figure instances,
perhaps so you can use them both interactively and as part of a
wxPython application.
If that's the case, I'd recommend you try using pylab's gcf() and draw
() to acquire and redraw the current Figure instance from within
IPython. You can also save the return value of pylab's figure(),
which returns a Figure that's already been attached to the
appropriate renderer. This way you can use the OO API for plotting
without having to futz with the drawing machinery directly.
This script might give you some ideas about how to structure your
code. It contains several of the MPL examples re-coded as functions
that accept a Figure instance and use the OO API for plotting.

[Matplotlib-users] pylab vs. embedding in wx
I have a problem that probably highlights a problem with how I
normally use mpl vs. how I should use it. I have some utility scripts
that do various data processing tasks and also have convenience
functions for plotting data using pylab. Almost all of my scripts
have a line like this near the top:
from pylab import figure, cla, clf, plot, subplot, show, ylabel,
xlabel, xlim, ylim, semilogx, legend, title, savefig
I am now trying to import some of my data processing functions into a
script that is embedding matplotib in a wxPython application following
the embedding_in_wx#.py examples. I am getting this error:

Re: [Matplotlib-users] how to set figure size
You have two options. savefig does have a dpi option that will
essentially set the figure size for the saved file:
savefig('myfile.png',dpi=300)
play with dpi until you get a figure size you like.
The other way to set the figure size is to specify it when you create
the figure:
figure(1,(10,8))
would create a fairly large figure. The figure (1 in this case) must
not already exist or at least it can't be shown on your screen
already. By that I mean if you have already called figure(1)
previously in your code, you must close it before you try to call
figure(1,(10,8)) or the figure size won't be affected.

Hi there,

rather than using 'show()' to show it, and this makes whole program
fully automatically, I don't know howto set the figure size before
'save' it (e.g. set size to 3000x1000pixel). The function 'savefig()'
doesn't have any option to set figure size. So which function should I

[Matplotlib-users] dvipng/miktex 2.5 usetex problem
I am trying to use latex with matplolib on Windows XP with MikTex 2.5
and dvipng 1.8.
I am getting this warning:
dvipng warning: font cmsy10 at 512 dpi not found, characters will be left blank
when I do this:
t=arange(0,1,0.01)
y=sin(2*pi*t)
plot(t,y)
and this
ylabel('$y(t)$')
leads to
dvipng warning: font cmr17 at 356 dpi not found, characters will be left blank
with no ylabel.
I am also getting a lot of other output (see below).
How do I fix this?
Thanks,
Ryan

Re: [Matplotlib-users] exponent fonts with usetex
It seems like no one has any comments on our plans concerning the
exponent fonts. Can you outline for me what it would take to fix
this? If it is fairly simple I may take a crack at it.

I agree that this little experiment of trying to work around latex's
limitations has been too much trouble. I suggest we go back to the old
behavior, and anyone who wants sans-serif fonts in their exponents can use
regular mathtext. I'm hopeful that Edin can make some strides with mpl's
mathtext support, and in the meantime, people should get decent results if
they set ps.useafm : True in their rc settings.
Comments?

I am afraid I asked you to open a can of worms and now I don't know
what we should do. With my font size settings, \small looks to small
for the exponents. I tried \normalsize and actually got decent
results with \large (replacing all occurances of \small in your
ticker.py). See that attached file. But if \small looked good with
your settings, I am afraid things are now dependent on the font
settings in the rc file as far as what should go in the latex command
for the exponents.
I remember that this problem came up because I complained about serif
fonts in my exponents and we were having a hard time making tex use
sans serif math fonts.
Maybe the best solution is for me to go back in time and retract that
complaint.
I don't know. Sorry about the mess this had made. I have plots I am
fairly happy with (I will poke around in my rc file and see if I can
find out why my x and y axis fonts look different).
