Re: [Matplotlib-users] overriding the save button

[Thomas R. <tho...@gm...>]

Hi John,

Thanks for your help!

I'm not sure how I should go about overriding the existing method. Say  
I have the following custom savefig():

def savefig(self, evt):
     print "Hello world"

and a figure() instance fig, how do I actually tell  
fig.canvas.manager.frame.toolbar.save to actually point to my custom  
savefig?

Thanks!

Thomas
