Reply To: How to fill the area under a curve with a color

Hello Bernd,

You may set the ChartType to 'Area’ as :

c1ChartBscan.ChartGroups[0].ChartType = C1.Win.C1Chart.Chart2DTypeEnum.Area;

Please refer to the attached sample depicting the same.

Let me know if this suits your requirement or not.

Regards,
