[Matplotlib-users] Controlling the wxpython matplotlib-frame
Hello all, I have trouble with one of my scripts that uses matplotlib when using python or ipython. The first time it opens, it does not hand the control back o the shell and can be used to work on the matplotlib figure interactively (I use an event handler and picker objects to change my plots) so it works really well. After I close the window the control is given back to the shell. This is how I want it to work, however at the second time the matplotlib plot opens the shell does not stop anymore, the script continues. When I used GTKAgg on my old linux box I had the same issue and bound a key to pylab.get_current_figure_manager().destroy(), which looked like a hack to me but worked. This does not work anymore with wxPython, because the next time I open a plot I get an exception: PyDeadObjectError: The C++ part of the FigureFrameWxAgg object has been deleted, attribute access no longer allowed. I also think destroying the figure_manager is not the right way to do that. Whats a goog solution for this?

[Matplotlib-users] windrose OO
Hi all, find with this message a modified version of windrose to be OO compliant. It uses inheritance from PolarAxes to create a WindroseAxes, with 4 methods (contour, contourf, bar and box). BTW it's now possible to control it like any other axes, with the limitation of subploting (subplot is to closer to simple axe and polaraxe). There's also a extra argument 'blowto' which reverse the plot (used in pollutantrose), and scipy is not required (just numpy).

Re: [Matplotlib-users] problems in Inkscape with SVG exported from matplotlib
When matplotlib outputs an SVG, each unique character is assigned a numeric id (these are just assigned in order), and inserted as a def, and then used (referenced) wherever they are used. When you paste on SVG into another, those names clash, and Inkscape is pulling in the wrong characters when it goes to draw. Now, my gut feels that this is actually a bug in Inkscape -- pasting of referenced objects from one file into another should reassign new ids. However, I'm not an SVG expert, so I could be wrong, but I think I will take this question over to the Inkscape mailing list anyway. That said, there are probably some workarounds that matplotlib could make (using a hash of the character's content as the id, for instance). I'll look into that and reply when progress has been made.

Re: [Matplotlib-users] problems in Inkscape with SVG exported from matplotlib
I didn't write the first pass of SVG support, that was done before I got involved -- I'm not sure who to credit, but he or she deserves most of it. I did add the feature that's causing grief here -- the embedding of character outlines directly in the SVG file. I've committed a change in SVN (both the trunk and the branch) that should resolve your problem. I've written the inkscape mailing list about the correct solution, but I figure we need a workaround in mpl regardless. If you're not tracking SVN, you can replace your copy of backend_svg.py with this one, and it should *probably* work: http://matplotlib.svn.sourceforge.net/viewvc/*checkout*/matplotlib/branches/v0_91_maint/lib/matplotlib/backends/backend_svg.py?revision=5023pathrev=5023 Cheers, Mike Kaushik Ghose wrote: Hi Mike, Ah, such prompt, friendly and knowledgeable help!

Re: [Matplotlib-users] draw_tex NotImplementedError in backend_bases.py
It looks like you're trying to use the Wx backend, where usetex is not
supported.
See here for a matrix of which features are supported with each backend:
http://matplotlib.sourceforge.net/backends.html
Set the backend setting in your matplotlibrc file or call
matplotlib.use at the top of your script.
Cheers,
Mike

Re: [Matplotlib-users] problems in Inkscape with SVG exported from matplotlib
For the sake of the list, I'm linking the response to my question on the Inkscape mailing list -- this is certainly an Inkscape bug, that their copy-and-paste functionality does not handle use/defs correctly. However, as the workaround in mpl was easy enough, we don't have to wait for Inkscape to fix what sounds like a difficult problem. http://sourceforge.net/mailarchive/forum.php?thread_name=3c78ff030803260851l36e71d12n173fb77d4ddc4579%40mail.gmail.comforum_name=inkscape-devel Cheers, Mike Kaushik Ghose wrote: Hi Mike, I replaced the current file with your modified one, and it works fine - I pasted three figures together and had not problems.

I did add the feature that's causing grief here -- the embedding of character outlines directly in the SVG file. I've committed a change in SVN (both the trunk and the branch) that should resolve your problem. I've written the inkscape mailing list about the correct solution, but I figure we need a workaround in mpl regardless. If you're not tracking SVN, you can replace your copy of backend_svg.py with this one, and it should *probably* work: http://matplotlib.svn.sourceforge.net/viewvc/*checkout*/matplotlib/branches/v0_91_maint/lib/matplotlib/backends/backend_svg.py?revision=5023pathrev=5023 Cheers, Mike Kaushik Ghose wrote: Hi Mike, Ah, such prompt, friendly and knowledgeable help!

Thanks again, -Kaushik Michael Droettboom wrote: When matplotlib outputs an SVG, each unique character is assigned a numeric id (these are just assigned in order), and inserted as a def, and then used (referenced) wherever they are used. When you paste on SVG into another, those names clash, and Inkscape is pulling in the wrong characters when it goes to draw. Now, my gut feels that this is actually a bug in Inkscape -- pasting of referenced objects from one file into another should reassign new ids. However, I'm not an SVG expert, so I could be wrong, but I think I will take this question over to the Inkscape mailing list anyway. That said, there are probably some workarounds that matplotlib could make (using a hash of the character's content as the id, for instance). I'll look into that and reply when progress has been made.

Do you know why this might be? I'm not sure I understand correctly, but if the number of xticks increases dramatically (nobody could see the individual ticks), Indeed, it looks like the Tick spacing is staying as it was when the first point was plotted, so when hundreds more points are plotted, I just get a jumble of labels on the x-axis. the above script leads to a different behaviour on my system. What is that behaviour and what version of matplotlib are you using?

[Matplotlib-users] capturing arrow key events

[Matplotlib-users] unicode filenames and MPL.
Hi all, I'm writing a little MPL embedded in wxPython app, and just ran into this: Traceback (most recent call last): ... ... /matplotlib-0.91.2-py2.5-macosx-10.3-fat.egg/matplotlib/backends/backend_agg.py, line 397, in print_png self.get_renderer()._renderer.write_png(filename, self.figure.dpi.get()) TypeError: cannot return std::string from Unicode object As soon as I saw it, I knew what happened: I'm running the unicode version of wxPython, so the filename I got back from a SaveFile Dialog is in unicode. Now, it's easy enough for me to turn that into a string for now, but as more and more file systems are implemented in unicode, it might be nice if we could use unicode file names with MPL. Are there any plans along these lines? Or are we just going to have to wait for py3k? -CHB -- 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.

[Matplotlib-users] saving a PNg jsut as dispalyed
Hi all, I want to save a figure just like it is displayed i.e. the same dpi (wxAgg). However, the default Figure.savefig uses a different dpi setting than the figure as displayed, so I'm doing: dpi = Fig.get_dpi() Fig.savefig(str(path), dpi=dpi) which seems to work, but seems more awkward than it should be.

Re: [Matplotlib-users] Fwd: load data from string or array to Image
I use matplotlib and Backend Agg to draw a plot , I want to show this plot in my GUI in specific area (Plot area) , I need to have the image object in oder to show it, so I have to convert this plot to string or array or save in buffer and then load it to an Image , I want to know , can I accomplish this without using PIL , because I need to build, test and verify any new package added to the system on 6 different platforms, and it might take a long time and at high expertise level to add the module to our entire system. What I have to do? I can convert it to string or array with numpy or FigureCanvas or ect. , my problem is how to load this array or string to image ! Is it clear?
