Hi Gurus:
I'm having a serious problem with MultiCursor and autoscaling...
If I do the code below with both MultiCursor instantiations commented out, then all plots are xscaled to [50,55] and yscaled to each plot's appropriate ylimits.
If I uncomment the top MultiCursor instantiation, then both the xlimits and ylimits are screwed up: xlim=[0,60] and ylim is all over the place, certainly not autoscaled tight.
If I uncomment the bottom MultiCursor instantiation, then the xlimit appears to be scaled correctly, [50,55], but two of the four plots (lower left and upper right) are not autoscaled in y.
How to I instantiate MultiCursor to get the normal and expected autoscaling behavior?
Not that it should matter, but I'm using here Tk and Python3 with MPL 1.5dev1 (91ca2a3724ae91d28d97)
Thanks for any help,
M
