[Matplotlib-users] Easy question: how to select specific subplot for second (or more) time

[Mark B. <ma...@gm...>]

Hello list -

I want to plot something in two subplots, then add something to the first
subplot.
How do I select the first subplot after I have plotted on the second
subplot?

For example:
subplot(211)
plot([1,2,3])
subplot(212)
plot([4,3,2])

Now I want to add something to the first subplot.
So I thought I could do subplot(211) again, but that destroys the subplot.
Any suggestions?

Thanks, Mark
