Hi,
Thanks for your reply :
I think I will try and follow your last suggestion by passing a callback
function that is defined through another function (this is because the
program generates a series of figures that are all similar) :
def gen_onselect(ax):
def onselect:
# do the stuff here that requires to know which axes
return onselect
and then use
span = SpanSelector(ax, gen_onselect(ax), 'horizontal', useblit=True,
rectprops=dict(alpha=0.25, facecolor='blue') )
I'll let you know if this works or not.
Kind regards,
Frederic
