Hi, I am building a wxPython app, and would like to try incorporating matplotlib, even though the wx backend is reportedly in its development state. Could someone please give a snippet of code using the wx backend? Also, do I need pygtk even though I intend on using wxPython? Thanks! jgw

The matplotlib code you write is more or less backend independent (same for gtk, wx, ps, etc..). You do not need pygtk. You just need wxpython and Numeric - which are both included in the enthought edition of python for win32, by the way; http://enthought.com/python. If you just want to make some figure windows to explore the plotting commands, you have 2 choices import matplotlib matplotlib.use('WX') from matplotlib.matlab import * plot([1,2,3]) show() or # myscript.py from matplotlib.matlab import * plot([1,2,3]) show() > python myscript.py -dWX That is, you choose the wx backend either by doing 'use' or -dWX. See http://matplotlib.sourceforge.net/backends.html for more info. See the examples dir of the src distro for examples of how to make plots more sophisticated than [1,2,3]. But I gather from your post that you want to see an example of embedding the plot in an application. Jeremy, the wx backend implemented, can probably help you more here. In the mean time, you might want to look at the FigureManagerWX class in the file matplotlib/backends/backend_wx.py to see how to embed a plot in a wx frame. I recommend you use the latest CVS, which has a number of improvements over the 0.32 release. If you don't have CVS access, let me know and I'll send you a snapshot (are you on windows). John Hunter
Thanks, that worked for being able to generate the [1,2,3] plot from within my application. Eventually I will want to embed into a wxFrame, but for now I think this should suffice. I'm actually on linux, and am using 0.32 for now. I will get the latest CVS when I am up and running. When do you expect to release the next version? Thanks again, jgw >>>>>> "John" == John Wohlbier <jd...@go...> writes: > > John> Hi, I am building a wxPython app, and would like to try > John> incorporating matplotlib, even though the wx backend is > John> reportedly in its development state.

I know Jeremy is planning on writing some example code to show how to embed wx in an application with or without the navigation toolbar, and possibly provide some utility classes to make it really easy. If you have bug reports or suggestions for improvement regarding the wx backend, the best place to send them is the matplotlib-dev mailing list - http://sourceforge.net/mailarchive/forum.php?forum_id=36187. There is a list of known bugs in header of the backend_wx.py code. John> I'm actually on linux, and am using 0.32 for now. I will get John> the latest CVS when I am up and running.

I ended up downloading the latest CVS using the command cvs -z3 -d:pserver:ano...@cv...:/cvsroot/matplotlib co matplotlib and doing python setup.py install Now when I run my application (which worked with version 0.32) I get this error on startup Traceback (most recent call last): File "./mptwt.py", line 3, in ? from mp_win import * File "./mp_win.py", line 10, in ? from matplotlib.matlab import * File "/usr/lib/python2.2/site-packages/matplotlib/matlab.py", line 121, in ? from axes import Subplot, Axes File "/usr/lib/python2.2/site-packages/matplotlib/axes.py", line 118, in ? import backends File "/usr/lib/python2.2/site-packages/matplotlib/backends/__init__.py", line 21, in ? from backend_wx import AxisText, Figure, FigureManager, Gcf, \ File "/usr/lib/python2.2/site-packages/matplotlib/backends/backend_wx.py", line 164, in ? from matplotlib._matlab_helpers import FigureManagerBase, GcfBase ImportError: cannot import name FigureManagerBase Am I doing something wrong? I guess I'll go back to version 0.32 for a while. By the way, when I run the python setup.py install command will the script properly overwrite the existing version of the matplotlib library, or should I go in and delete the old library first?
