I wish to make a RangdSpline series with a gradient. Similar to what is done in the SurfaceSeries3D

Is this possible in 2D?

Hello Karl,

This is not supported by the 2D charts. Maybe you could achieve your requirement by creating a custom gradient brush and applying it to the Fill property of the RangeSplineSeries. However, the success of this approach depends on how exactly you want to color the data. Basically, you can create a LinearGradientBrush and calculate its GradientStop objects based on the data plotted in the series. Then set the brush to the Fill property. Can you try this and let me know if it helps?

Also, we have a feature request for implementing a contour plot visualization - similar to the 3D surface series. 

Also, you can consider using an approach with the 3D surface series. In this case you can try to rotate the camera of the chart (using its Camera property) so that the chart is displayed from a top.

The gradient stop approach could work but that will require some calculations to get it correct.

I was unable to get the 3D surface series to work work like I expected. I have started another post in the 3D chart view forum.
