I'm looking to create a chart with both an area as well as a line that tops it. BorderStyle draws a line all of the way around the area, but I don't want the line to go all of the way around, I only want it on top of the area. The effect I'm looking for would be if there was an NLineSeries with the same data as the NAreaSeries.

The problems with using two series are that 1) it colors the line differently than the area, and 2) it adds extra legend entries.

Does BorderStyle have an ability to border only on one side? Or is there another way to go about this?

Thanks.
