[Solved] Shaded area between two LineSeries

[david mcintyre]

I am trying to figure out how to shade the area between 2 line series.  Visually, the shaded area would look like a Bollinger band indicator, but in my case the upper and lower bound of the shaded area need their own independent data series.  I've been able to partially accomplish this by overlaying two ScatterSplineAreaSeries (the chart has a white BG, and the upper area series has a dark BG, and the lower has white BG) but the problem is that the lower series also hides the gridlines.  Is there any way to do this?  Screenshot of this is attached.

Hi David,

Thank you for the question.

Unfortunately, the current version of the RadChart control does not support such functionality.

There is a possible solution if you use categorical stacked series and custom palette with transparent color for the lower series. In this case you have to calculate new values for the upper series in order to be positioned properly(take into account the values of the lower series). 

I hope this gives you some ideas. Please, let us know if there is anything else we can assist you with.
