Hello Telerik Team,

I was wondering how one would implement error bars in a ScatterPointSeries that look similar to this: https://demos.telerik.com/kendo-ui/line-charts/error-bars

There is a very similar question that has been asked before (https://www.telerik.com/forums/how-to-plot-error-bar-for-standard-deviation). Unfortunately, it doesn't look like the feature request mentioned there is going to be implemented anytime soon. As a workaround it was suggested to use a RangeBarSeries with a custom PointTemplate, but that will not work for me, since it is a Cathegorical series and I need to plot the data points at any arbitrary xy coordinate, which is my reason to use the ScatterPointSeries.

I was researching further and found someone mentioning a custom renderer but it seems that is only applicable for windows forms.

I also found this site https://docs.telerik.com/devtools/wpf/controls/radchart/how-to/howto-create-scatter-errorbars-and-boxplot-series but it seems to only work for RadChart and not RadCartesianChart.

Any pointers in the right direction would be greatly appreciated.

 

Best Regards,
Robin

Hello Robin,

Indeed, the SDK example showing how to create custom error bar visual is applicable only for the categorical series. However, you can use the same approach also with a scatter one. The main idea is the same - you can use one of the already presented series and replace its default visuals with a custom one, using the PointTemplate. I've updated the SDK example's project to show how to create a custom visual for the scatter series. I hope that the attached project helps.
