py-matplotlib could have variant tk

[than@…]

I like to use the interative version of py-matplotlib (where you don't always have to type show() after each plot command). This only works with the tkAgg backend, which is disabled for some reason in the current Portfile.

I would actually argue that tkAgg should be enabled by default, but I leave that to wiser heads than mine. I used the following patch to the py-matplotlib Portfile to enable the tkAgg backend as a variant:
