public enum ConstantLineTitleAlignment
<ResourceFinder(GetType(XtraChartsResFinder), "PropertyNamesRes")>
Public Enum ConstantLineTitleAlignment
| Name | Description |
|---|---|
Near |
Specifies that a constant line title is aligned near to the axis which it belongs to.
|
| Far |
Specifies that a constant line title is aligned far from the axis which it belongs to.

The following properties accept/return ConstantLineTitleAlignment values:
| Library | Related API Members |
|---|---|
| Cross-Platform Class Library | ConstantLineTitle.Alignment |
| WinForms Controls | ConstantLineTitleModel.Alignment |
The values listed by the ConstantLineTitleAlignment enumeration are used to set the ConstantLineTitle.Alignment property of a constant line.
For more information, refer to Constant Lines.
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;
' Cast the chart's diagram to the XYDiagram type, to access its axes.
Dim diagram As XYDiagram = CType(chartControl1.Diagram, XYDiagram)
' Create a constant line.
Dim constantLine1 As 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
