[Matplotlib-users] OS X leopard scisoft and TkAgg backend
Dear all, I use the scisoft package on leopard 10.5.2 (it is a package that creates its own python framework and delivers astronomical tools). I have recompiled tcl tkk 8.4 and 8.5 (which in hindsight was probably not a good idea). I also installed matplotlib 0.91.2. If i open ipython --pylab and do : plot([1,2,3]). I get the following output: FigureCanvasAgg.draw RendererAgg.__init__ RendererAgg.__init__ width=640.0, height=480.0 RendererAgg.__init__ _RendererAgg done RendererAgg.__init__ done Segmentation fault thanks in advance Wolfgang - This SF.net email is sponsored by: Microsoft Defy all challenges.

[Matplotlib-users] Integrating plots with existing PyGTK application
Hi everyone,
I am a developer on a PyGTK application for Earth Science research and
education called SEATREE ( http://geosys.usc.edu/projects/seatree/wiki )
and we are trying to integrate some pylab plots.
I can successfully create and use a pylab frame/window inside of our GTK
application using the following sequence (note that all of this is
called AFTER the application has launched and the GTK main loop has
started):
-
import math
import pylab as p
import matplotlib
from matplotlib.backends.backend_gtk import FigureCanvasGTK,
NavigationToolbar
matplotlib.use('GTK')
p.figure()
//set up the figure
//connect actions using p.connect('signal name', function)
p.show()
-
Then, once I'm done with the plot and it is closed, p.close() is called.
All of that works fine, and I actually like the blocking nature of the
p.show() method (I know this probably isn't the best way since I already
have a GTK main loop going). The problem arises when I try to display
the plot again. If I just call the p.show() method for a 2nd time, it
does not block execution of my function, and the plot shows up but is
unresponsive with full CPU utilization. My main GTK window for the
application is enabled and responsive during this time.
I then tried using the following code to show the window (either both
times or just the 2nd time around):
-
for manager in Gcf.get_all_fig_managers():
manager.window.show()
-
But I get an error that is very strange, as it references Tkinter even
though I am using GTK:
-
Traceback (most recent call last):
File
"/home/kevin/workspace_seatree/SEATREE/py-drivers/py-hc/flowGUI.py",
line 379, in editVisc
manager.window.show()
File "/usr/lib/python2.5/lib-tk/Tkinter.py", line 1724, in __getattr__
return getattr(self.tk, attr)
AttributeError: show
-
Finally, I tried just not calling anything after p.frame() the second
time through (besides doing the signal connecting again), and this time
the plot window will show up, but signals will not be processed
(including trying to close the plot with the 'x' on the window frame).
I also tried just embedding a FigureCanvasGTK object displaying the
figure to my own gtk.Dialog object, which works for displaying the plot,
but I couldn't figure out how to get the pylab events to be processed
and connected (I need to modify the plot by clicking on parts of it). If
I could figure out the even handling, this would actually be the
preferred method of showing the plot. This is the code for this attempt:
-
self.dialog = gtk.Dialog(title=title, parent=parent, flags=
gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT)
self.canvas = FigureCanvasGTK(self.figure)
self.dialog.vbox.pack_start(self.canvas)
self.dialog.show_all()
self.dialog.show()
-
Does anyone have any suggestions? Thanks a ton for making it this far
through my long message!

debugging stages)

For the "use" directive to be honored, it must be called before you
import pylab. If it is after, as in your example code, pylab will
respect the setting in your matplotlibrc file -- see
http://matplotlib.sf.net/matplotlibrc (this is likely why you are
getting unexplained references to tk code).
But you should not be using pylab, since you are embedding mpl in a
GTK GUI. Instead, you should be using the matplotlob API,
specifically the idioms for embedding mpl in gtk -- it takes a little
more work up front but it is the only acceptable way to use mpl in a
GTK app
http://matplotlib.sf.net/examples/embedding_in_gtk.py
http://matplotlib.sourceforge.net/examples/embedding_in_gtk2.py
See also the OO FAQ and the API tutorial for more insight into using
the API directly rather than the pylab interface

Given the frequency of this question, maybe it would be a good idea on the main project page http://matplotlib.sourceforge.net/> to augment the text The plotting functions in the pylab interface have a high degree of Matlab® compatibility. to include a caveat: The plotting functions in the pylab interface have a high degree of Matlab® compatibility. (These are suitable for plotting scripts but NOT for GUI embeddding, which should use the matplotlib API.) fwiw, Alan Isaac - This SF.net email is sponsored by: Microsoft Defy all challenges.
