The following chart shows the result of using TPointSeries

This is an altitude profile and shows that there is an upper trace (see top right half of chart) and a lower trace (bottom left) in the source data. The data is entered into the Series in the order collected and I would like to see lines connecting the points.
The following chart shows the result of using TLineSeries.

The points are connected in ascending x-axis order and not in the input order. This produces the zig-zag connection which is not what is desired.
I want a TPointLineSeries that is a hybrid of these 2 series and connects the points in the order entered.
