Re: [Matplotlib-users] Agg backend problem with 0.53

[Gary R. <ga...@em...>]

I shouldn't have jumped to conclusions. Agg seems OK. GTKAgg works from SciTE and IDLE just using show().
If I substitute this:

manager = get_current_fig_manager()
manager.window.show()
raw_input('paused')

then a window is opened but nothing is painted onto the canvas area from either IDLE or SciTE.
It looks like GTKAgg might be the backend of choice for these environments.
