Examples
The following code example demonstrates how to add a threshold line after the chart control has been added to the design surface. The chart uses a non-recurring strip line to show a calculation of the mean of all data points in a series.
Imports System.Web.UI.DataVisualization.Charting
Public Partial Class StripLines
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
' Add chart data before adding strip lines.
AddChartData()
' Adds a threshold line using strip lines.
AddThresholdStripLine()
End Sub
''' <summary>
''' Adds a week of data with values between 20 and 35.
''' </summary>
Private Sub AddChartData()
' Declare new random variable
Dim rand As New Random()
For i As Integer = 0 To 6
' Add a week of data
chart1.Series(0).Points.AddXY(DateTime.Now.AddDays(i), rand.[Next](20, 35))
Next
End Sub
''' <summary>
''' Adds a horizontal threshold strip line at the calculated mean
''' value of all data points in the first series of the chart.
''' </summary>
Private Sub AddThresholdStripLine()
Dim stripLine3 As New StripLine()
' Set threshold line so that it is only shown once
stripLine3.Interval = 0
' Set the threshold line to be drawn at the calculated mean of the first series
stripLine3.IntervalOffset = chart1.DataManipulator.Statistics.Mean(chart1.Series(0).Name)
stripLine3.BackColor = Color.DarkGreen
stripLine3.StripWidth = 0.25
' Set text properties for the threshold line
stripLine3.Text = "Mean"
stripLine3.ForeColor = Color.Black
' Add strip line to the chart
chart1.ChartAreas(0).AxisY.StripLines.Add(stripLine3)
End Sub
End Class

}

// Set threshold line so that it is only shown once
stripLine3.Interval = 0;
// Set the threshold line to be drawn at the calculated mean of the first series
stripLine3.IntervalOffset = chart1.DataManipulator.Statistics.Mean(chart1.Series[0].Name);
stripLine3.BackColor = Color.DarkGreen;
stripLine3.StripWidth = 0.25;
// Set text properties for the threshold line
stripLine3.Text = "Mean";
stripLine3.ForeColor = Color.Black;
// Add strip line to the chart
chart1.ChartAreas[0].AxisY.StripLines.Add(stripLine3);
}
}

Use this property to add text to a strip line.
