Error Bars

Weather in Los Angeles, California

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:

  1. Add a DxChartSeriesValueErrorBar object to series markup.
  2. Specify source fields or calculation method for error bar values.
  3. Optional. Specify error bar display mode.
  4. 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.
