Hello,
on matplotlib 1.0, using qt4agg backend, the 'edit curves and lines' option
doesn't works.
This is a quick patch that fix that problem.
It doesn't fix this snippet though:
(on lib/matplotlib/backends/qt4_editor/formlayout.py, FormWidget.setup)
elif isinstance(value, (list, tuple)):
selindex = value.pop(0)
tuple don't have pop.
However with the patch this bug is not triggered anymore.
Thanks!
Riccardo
