Hi,
I'm wondering if it is possible to use SpanSelector on multiple figures : my problem is that I can't think of a way to tell the onselect on which axes(ses) of which figure it should try and do something. The example works because there is only one SpanSelector active and "it" therefore knows which axes "it" should redraw.
For it to work on multiple figures (say I have a series of events that I plot in a similar way each in a separate figure and I would like a SpanSelector feature on each of the figures) I would need to have a reference to which axes called the onselect through SpanSelector : then I could get the axes's figure and manipulate the other subplots on that figure accordingly.
Is there a way of doing this ?
Kind regards,
Frederic

Mouse event in mpl has a "inaxes" property. However, SpanSelector hide
event information from users.
On the other hand, the first argument of the SpanSelector is the
"axes" that you want to use. So, I'm not sure what your point is. You
already know the axes you're working with. Can't you just use
different callbacks for different axes?

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

I think this is common practice in event handling.
The partial function can be handy.
