Goals: date plot with two y axes (plotting completely different things)
point picking and point labeling
As many lines as user wants, all colored differently.
Having some problems with this. (matplotlib 0.98.5)
1) There is a known bug with twinx() and plot_date:
http://sourceforge.net/tracker/index.php?func=detail&aid=3046812&group_id=80706&atid=560720
But I can get it to work if I change ONE OF the plot_date() calls (the
one for the values plotted to the right-hand y axis) to just plot().
Is that going to introduce problems? Is there a better workaround?
(The ones on that page don't work for me).
2) How can I get the lines belonging to different axes to cycle
through colors such that the same color is not used for any lines
shown in the plot? (that is, I don't want to hard code a color to any
line, I want it to auto-cycle).
3) My point picking is not working with the two axes. In my routine,
I label the picked point and to do that I have to make reference to
its axis and call plot_date(). How can I know which axis the picked
point came from, so that I can label it appropriately?
Sorry this is a little stirred together, but hoping I can get some
hints to allow me to work it into shape.
Thanks,
Che
