How to: Plot the Fixed Value Error Bars Indicator on a Chart

• Nov 18, 2021

This example demonstrates how to plot Fixed Value Error Bars on the chart.

To do this, add a FixedValueErrorBars object to the series view’s XYDiagram2DSeriesViewBase.Indicators collection. Then, define negative and positive error values using the FixedValueErrorBars.NegativeError and FixedValueErrorBars.PositiveError properties.

Form1.cs

PointSeriesView view = (PointSeriesView)chartControl.Series[0].View;
view.Indicators.Add(new FixedValueErrorBars {
    NegativeError = 7,
    PositiveError = 10,
    Direction = ErrorBarDirection.Both,
    ShowInLegend = true,
    Name = "Unit Price Range"
});

Form1.vb

Dim view As PointSeriesView = CType(chartControl.Series(0).View, PointSeriesView)
view.Indicators.Add(New FixedValueErrorBars With {.NegativeError = 7, .PositiveError = 10, .Direction = ErrorBarDirection.Both, .ShowInLegend = True, .Name = "Unit Price Range"})
