Statistics tool makes easy to add basic functions to series, like Average, Trend, etc.And also shows a report with basic statistical information about the selected series. You can find a simple example in the TeeChartActiveX Demo project, concretely, All feature\Tools\SeriesStats or taking a look in next simple example of code:
Private Sub Form_Load()
With TChart1
.AddSeries scLine
.Series(0).FillSampleValues 100
.Tools.Add tcSeriesStats
.Tools.Items(0).asSeriesStats.Series = TChart1.Series(0)
' Add a series to be used for an Average Function
.AddSeries scLine
'Define the Function Type for the new Series
.Series(1).SetFunction tfAverage
.Series(1).DataSource = .Series(0)
Text1.Text = .Tools.Items(0).asSeriesStats.Statistics.Text
End With
End Sub
I hope will help
Thanks,
