[Matplotlib-users] Fwd: Keep list of figures or plots and flip through list using UI

[Thomas C. <tca...@gm...>]

A good tutorial on how to make mpl play nice with QtDesigner would be a
useful thing to have in the documentation.  It would be appreciated if you
could take a crack at writing that up.

Funny thing - shortly after I wrote you - I figured it out.  I have a
GUI/Dialog I created with designer that has a push button which cycles
between two plots I stored in a list.  If you would like to see my
code, I would be more than happy to share.  It isn't fabulous, but it
show the mechanics.  I will also take a look at what you just posted
above.

Much appreciated!
