Property Value
Type | Description |
---|---|
Object | A Object value that specifies the constant line’s position. |
Remarks
The AxisValue property specifies the position of a constant line along its corresponding axis. The value set for the AxisValue property should lie in the range specified by the AxisBase.Range property in order for the constant line to be visible on a diagram.
The following images demonstrate the AxisValue property in action.
AxisValue = 350 | AxisValue = “Indiana” |

Example
This example demonstrates how a constant line can be created and customized at runtime.
Since constant lines belong to a diagram’s axis, it’s first required to cast your diagram object to the appropriate diagram’s type. After that, it’s possible to access axes and manage their constant lines collection.
// Cast the chart's diagram to the XYDiagram type, to access its axes.
XYDiagram diagram = (XYDiagram)chartControl1.Diagram;
// Create a constant line.
ConstantLine constantLine1 = new ConstantLine("Constant Line 1");
diagram.AxisY.ConstantLines.Add(constantLine1);
// Define its axis value.
constantLine1.AxisValue = 7;
// Customize the behavior of the constant line.
constantLine1.Visible = true;
constantLine1.ShowInLegend = true;
constantLine1.LegendText = "Some Threshold";
constantLine1.ShowBehind = false;
// Customize the constant line's title.
constantLine1.Title.Visible = true;
constantLine1.Title.Text = "Constant Line Title";
constantLine1.Title.TextColor = Color.Red;
constantLine1.Title.Antialiasing = false;
constantLine1.Title.Font = new Font("Tahoma", 14, FontStyle.Bold);
constantLine1.Title.ShowBelowLine = true;
constantLine1.Title.Alignment = ConstantLineTitleAlignment.Far;
// Customize the appearance of the constant line.
constantLine1.Color = Color.Red;
constantLine1.LineStyle.DashStyle = DashStyle.Dash;
constantLine1.LineStyle.Thickness = 2;
