SASS Theme Builder
This demo illustrates how to show variability of data using the Error Bars feature of the Telerik Core Bar Chart. The Error bars are specified as part of the Series setting and are offered by the following Series types: Area, Vertical Area, Column, Bar, Line, Vertical Line, Scatter and ScatterLine.
The error bars support statistical calculations based on the series data. The supported types are standard error and population standard deviation. To specify that standard error should be used, you need to set "stderr" as a value, i.e.
Series -> Column-> .ErrorBars(errorBars => errorBars.Value("stderr"))
You can find more information in the following help article: Error Bars.
