matplotlib 0.86.2 python 2.4.1 wxPython 2.6.2.1 Mac OS X.4.7
I draw a circle at a certain point. I let the user drag that point to a new location. However, if the plot is redrawn for any reason, I have to redraw my circle in a new position. I can't seem to find any way to get notified of a redraw.
Figure.add_axobserver() isn't fully implemented as far as I can tell since it only notifies for a artist deletion or a call to sca(). Axes.connect() doesn't work either because there's no way to set emit in a class-wide scope and consequently calls made to set_xlim made by the toolbar do not trigger an event because they lack the emit keyword in their calls. Here's the relevant code from axes.py.
def set_xlim(self, *args, **kwargs):
# .....
emit = popd(kwargs, 'emit', False)
# .....
if emit: self._send_xlim_event()
return vmin, vmax
I've been trying to accomplish this without editing matplotlib
package code. Is there a way I could override Axes.set_xlim() in
order to insert "emit=True" into the arguments?
Maybe there's a better way to do what I'm doing? Thanks, R.
