Area Charts / Error Bars
This demo illustrates how you can use Error Bars for ASP.NET MVC Area Chart to show variability of data. The Error bars are specified as part of the Series chart 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, population standard deviation and other. To specify that standard deviation, you should set "stddev" as in this demo, i.e. Series -> Area -> ErrorBars(errorBars => errorBars.Value("stddev"))
You can find more information in the following help article: Error Bars.
