Hello and thanks for this OS library
I'm trying to use PlotfillAboveBelow but I get inconsistent result

I'm using dotnetcore 3.1 and I'm rendering in memory and this is the result

How you can see, points above and below doesn't connect properly
If i print same data using bars, these are this is the output

(the green line is a vertical span set at the same height of the baseline of the 1st chart)
how you can see the 1st chart shouldn't have overlapped areas.

Thanks.
