Hi, I'm using matplotlib embedded in my wxpython application and needed to give users a quick way to relimit a figure, for example after removing a line from a plot. Therefore I added a button to the toolbar. Do you think it would make sense to include this in matplotlib by default? Appended you find modifications of backend_bases.py and backends/backend_wx.py as well as a draft for a symbol.
Greetings, Dieter
