Thanks - we'll look into that. We might also see how hard it would be to implement an update or refresh method on the legend that could be called when the lines change to keep the legend in sync. Seems like the legend should own that functionality since it set up the mapping between the lines and what it's displaying...

You can use the set_color() method on them. Maybe this is enough if your application is simple enough.
