Hi Jason, Thanks for that! How ironic that it does not work for non-linear functions! I actually played around with p.matplotlib() before I found your reply, but I haven't got it to plot anything. Is there a step I am missing before I can import a plot() into pylab and manipulate it there? That would be a great feature!
