I was wondering if you ever got to create a small GUI program that did plots
using Matplotlib
I am gettin an error where its saying "WXagg's accelerator requires the
wxPython headers-the wxpython header files can not be located in any of the
standard include directories reported by 'wx-config --cppflags'
Do you think you can help?
