Do you know if there is a reason why I cannot succeed in generating a
pick_event using wxmpl?
I know I could use EVT_POINT but I need the picker event to return the event.ind
thanks!

Yes, WxMpl disables all matplotlib events to ensure that figure zooming works correctly. I haven't had time to ensure that WxMpl will work reliably in all cases when matplotlib's events are enabled.

Although it's a bit silly, one possible solution would be to have your EVT_POINT callback generate a mouse event. I think something like this might work, but I haven't tried it...
from matplotlib.backend_bases import FigureCanvasBase
def OnPoint(evt):
figureCanvas = evt.axis.figure.canvas
FigureCanvasBase.button_press_event(figureCanvas, evt.x, evt.y, 1)

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
