Force ScatterAreaSeries to fill area toward negative Y value instead of around zero

[Prakit]

By default, ScatterAreaSeries / ScatterSplineAreaSeries seems to fill the area around Y = 0 axis (the blue).

I want ScatterAreaSeries / ScatterSplineAreaSeries to fill the area below the data point with negative Y value (the yellow area).

How can I achieve the yellow area with ScatterAreaSeries / ScatterSplineAreaSeries ?

Also, are there any Annotation / Series to fill the shape like yellow area?

Hello Prakit,

To make the area series to star drawing from a value different than 0, set its OriginValue property. For example:

<telerik:ScatterSplineAreaSeries OriginValue="-50" />

To draw the yellow area from your picture you can use another ScatterAreaSeries.

I hope that helps.

Hello Martin,

Thank you very much for your help.
Per your suggestion, I use another ScatterAreaSeries with some addition data points to draw the yellow area.
It works perfectly!

Anyway, I want to point out that OriginValue property is not found in UWP chart (although it exists on WPF from your link).
