How to add striplines to an axis in a WinForms Chart?

In WinForms Chart control, StripLines are visual bands drawn in the background of the chart to highlight specific ranges or thresholds on the X or Y axis. They can be vertical (along the X-axis) or horizontal (along the Y-axis), and are commonly used to mark target zones, maintenance windows, danger thresholds, or weekend ranges.

StripLines are stored in the Axis.StripLines collection of a ChartArea and are instances of the StripLine class.

Create and add Stripline to Chart:

A stripline can be added to an axis by using the StripLines.Add() method. The starting position, ending position, and width of the stripline can be configured using the Start, End, and Width properties, respectively. Additionally, the interior style can be applied using the Interior property.

// Creating a Stripline

private ChartStripLine XLine = new ChartStripLine();

XLine.Enabled = true;

XLine.Vertical = true;

// Specifying its position

XLine.Start = 2;

XLine.Width = 0.5;

XLine.End = 3;

XLine.Text = "XLine";

XLine.TextColor = Color.Blue;

XLine.TextAlignment = ContentAlignment.MiddleCenter;

XLine.Font = new Font(XLine.Font.FontFamily.Name, 12);

XLine.Interior = new BrushInfo(230, new BrushInfo(GradientStyle.Vertical, Color.LightYellow, Color.Yellow));

// Adding to the Axes

this.chartControl1.PrimaryXAxis.StripLines.Add(XLine);

'Creating Stripline

Dim XLine As ChartStripLine = New ChartStripLine()

XLine.Enabled = True

XLine.Vertical = True

' Specifying its position

XLine.Start = 2

XLine.Width = 0.5

XLine.End = 3

XLine.Text = "XLine"

XLine.TextColor = Color.Blue

XLine.TextAlignment = ContentAlignment.MiddleCenter

XLine.Font = New Font(XLine.Font.FontFamily.Name, 12)

XLine.Interior = New BrushInfo(230, New BrushInfo(GradientStyle.Vertical, Color.LightYellow, Color.Yellow))

' Adding to the Axes

Me.ChartControl1.PrimaryXAxis.StripLines.Add(XLine)
