Re: [Matplotlib-users] pick_event with wxmpl

[Giorgio F. G. <gi...@gi...>]

Thank you Ken,
I ended up doing more or less as you suggested but it turns out that
with the new pick API is actually much easier:

    wxmpl.EVT_POINT(self, self.GetId(), self.onPoint)
    self.mpl_connect('pick_event', self.onPick)


    def onPoint(self,event):
       '''
       Called by the EVT_POINT of wxmpl. Generates a pick_event
       '''
       event.axes.pick(event)

    def onPick(self,event):
       '''
       Called upon a pick_event
       '''
       print 'You picked %s' % event.ind
