Is there a better interactive plotter then pylab?

[Charles Krug]

List:

I'm trying to us pylab to see what I'm doing with some DSP algorithms,
in case my posts about convolution and ffts weren't giving it away.

I've been using pylab's plot function, but I'm finding it a bit
cumbersome.

It works, but if I switch from the interactive window to the plot window
and back, the plot window gets trashed.

Is there a better alternative for interactive use?

Thanks
