Hi,
how could I realize a moving marker line under the mouse pointer?
I know about event handling
http://matplotlib.sourceforge.net/users/event_handling.html
and would use ‘ axes_enter_event’ to react on, then draw a line
with
axvline(x=event.xdata, linewidth=1, color='r')
but how can I delete the line again without deleting my whole plot
I have on that axes/subplot?
Also I didn't see any "mouse move" event that would recognize a
change in cursor position? Or is that what is meant with
'motion_notify_event'?
If that is so, it comes down to know how to delete a vertical line on
a mouse_notify_event. Is there a way to get a (named) list of plots
on a particular subplot?
In a different context I tried to keep my on list in a python
self.axes list, but that was very tedious and I didn't finish
it to work properly.
Cheers,
Sven
