Remarks

Error bars are used on charts to indicate an error or an uncertainty in a reported measurement. They give a general idea of how precise a measurement is.

In BootstrapPolarChart, an error bar is a vertical bar with two marks at its edges. An error bar accompanies a series point. Error bars can be generated either from concrete or calculated values. To generate one error bar, two values, high and low, are needed. If the data source of your chart provides concrete high and low values, assign the required data source fields to the BootstrapChartValueErrorBarSettings.HighValueField and BootstrapChartValueErrorBarSettings.LowValueField options.

Alternatively, error bar values can be calculated according to an algorithm. In this case, choose the required algorithm using the BootstrapChartValueErrorBarSettings.Type property, and specify the value to be used in calculation using the BootstrapChartValueErrorBarSettings.Value property.
