Error bars indicate measurement precision or uncertainty. They display a possible value range next to a series point. Error bars can display fixed values or percentages, statistical function values, or error values obtained from data source fields.
To configure error bars for a series, you must:
- Add a DxChartSeriesValueErrorBar object to series markup.
- Specify source fields or calculation method for error bar values.
- Optional. Specify error bar display mode.
- Optional. Customize error bar appearance.
In this demo, the bar series displays fixed-value error bars. The line series obtains its error bar values from data source fields.
