This is yet another example of using matplotlib with wx. Hopefully
10+
this is pretty full-featured:
11+
12+
- both matplotlib toolbar and WX buttons manipulate plot
13+
- full wxApp framework, including widget interaction
14+
- XRC (XML wxWidgets resource) file to create GUI (made with XRCed)
15+
16+
This was derived from embedding_in_wx and dynamic_image_wxagg.
17+
18+
Thanks to matplotlib and wx teams for creating such great software!
