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

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

        ' Add chart data before adding strip lines.

        ' Adds a threshold line using strip lines.
        AddThresholdStripLine()
    End Sub

            ' Add a week of data
            chart1.Series(0).Points.AddXY(DateTime.Now.AddDays(i), rand.[Next](20, 35))

        ' Set threshold line so that it is only shown once

Remarks

Use this property to add text to a strip line.
