Re: [Matplotlib-users] using subplot to plot a large numbers of graphs in a loop

[Ryan K. <rya...@gm...>]

I think you need to replace plot(x,y) with ax.plot(x,y).

I think this script could be slightly simpler if you used the pylab
interface to matplotlib so that you could just call figure, subplot,
and plot without having to specify the axis.

But if this is your first attempt at using matplotlib, you have done a
fairly impressive job at searching the examples and archives first.
