Feature Suggestion

Feature description:
I'm attempting to create a FillY plot with 2 series 1 for power usage and 1 for Solar power generated I'm currently able to get it to look the way I'm wanting by using the FillY and setting the second series to all 0's so it just fills from my data point to the x-axis. However I would like to still have a Legend and it appears that the FillY doesn't have a Label to set and is hardcoded to always return no LegendItems

I can't imagine I'm the only one who wants to do something like this;
What I'm currently getting:

Scatter with the same plot but with legend:
