I'm using Matplotlib to present a "control" window with clickable
buttons, and to plot things in another window when you click buttons,
in the style of the code below. I'm ashamed of the stinky way I
use "first" to call plt.show the first time data are plotted but then
to call fig.canvas.draw for

This is tremendously inefficient. It demands a context switch for

Inefficiency isn't an issue when you generate one byte a second.
Of course, but who's doing one byte per second? You and I in our

It defines a few functions, but nothing ever calls them, so you won't
see much out of it :) Try adding some code at the bottom that actually
calls one of your function

Hi!
Start here. If we can't help, python-dev might be the next place to
ask,
Hello,
If I have a problem with building Python on an Android device, would
