Matplotlib in wx application segfaults when plotting
I am writing my first wx application in python as a frontend to plotting in matplotlib. I successfully get my data into numpy arrays angles and col_cnts. However when I issue plt.plot I get the following error
usr/lib64/python2.6/site-packages/matplotlib/backends/backend_gtk.py:621: DeprecationWarning: Use the new widget gtk.Tooltip
Segmentation fault (core dumped)
My code is appended. I am not sure where to even start with debugging. I have tracked it down to the plt.plot line but in the absence of further information I am lost. I am running python 2.6 on rhel 6.4

EDIT
I have now managed to split my panel into upper and lower panels. However the space management is quite poor. Big gap between last NumCtrl and buttons in upper panel. Also I do not know how to position my figure centrally within the lower panel and resize it according to panel size

You need to create a figure with code similar to:
import matplotlib as mpl
mpl.use('WXAgg')
import matplotlib.backends.backend_wxagg as mwx
fig = mpl.figure.Figure()
canvas = mwx.FigureCanvasWxAgg(panel, -1, fig)
ax = fig.add_subplot(1, 1, 1)
ax.plot(...)
canvas.draw()
See the Matplotlib Example gallery for a runnable example.
