Toggling country boundaries in MPL Basemap

Community matplotlib-users
#1

Dear ALL,

Always engaged in pushing MPL/Basemap ahead of its limits, here am I
again with a humble question: I want to be able to toggle the display
of country boundaries on a map using a menu option on my wxPython
interface. It is quite easy to initially plotting a map without
borders and then toggling them on, but I could not figure out a way to
toggling them off (if possible, without redrawing the whole map). Is
there any trick to do this? :wink:

Thanks in advance!

With warmest regards,

The drawcountries() method returns a matplotlib line collection. Invoking the remove() method of the line collection will remove the countries from the axes instance.
