Hello, Nathan,
By design,
RadChartView renders a
ChartGrid when the CartesianArea.
ShowGrid property is set to
true. The CartesianArea.
Grid exposed several properties that you can customize the style of the background grid behind the series. However, it allows you to alternate the colors. In case you need to achieve the illustrated result on the screenshot, you can use
CartesianPlotBandAnnotations. Thus, you can specify the values ranges of the two annotations and the color you want to be used for filling the area. Additional information for the
CartesianPlotBandAnnotations is available here:
https://docs.telerik.com/devtools/winforms/chartview/features/annotations/plot-band
I hope this information helps. If you have any additional questions, please let me know.
Regards,
Dess
