Title: Legend multi series

Hi, I have a need to graph the same series in multiple ways. I've updated the legend to look for series that have the same name and group them. I've also updated toggle, highlight, and order to be able to cope with each legend item holding multiple series. If, in a future extension, the legend items are grouped on another criteria, order/toggle/highlight should not need updating (only legend).
