Thank you for finding this! That is indeed the case. I think we need to rework the plot generation code to avoid side effects by forcibly resetting state between plots. Maybe we should just fork another Python process for each plot. Darren, since (I believe) you wrote the initial documentation plotting code, do you have any thoughts?
