I have an AreaSeries where some data points are above the BaseValue, but some data points are below the BaseValue. I expected that a "negative" area would be drawn for those points, but instead a horizontal line at the BaseValue is drawn.

Can you add the functionality to draw negative areas?

HighLowSeries is intended for the usage you described. Please use that.

I knew you were going to say that. I already tried that and it doesn't always work. It works when there's a data point exactly at the base line, like this:
But it doesn't work when the data points skip the base line:
A true area chart would have drawn a line crossing the base line. So that's why I added this feature request.

Thanks,

As a workaround I tried using a PolygonSeries, but it doesn't get filled right when vertices cross each other. So please, can you improve the AreaSeries???
