Hi,

not all the Series type can be changed dinamically. This depends on which type of values are stored in the Series. For example Arrow Series and Shape series, specifically, require values of type (X0,Y0) and (X1,Y1) whereas a BarJoin series only requires (X,Y) so this could not be changed. To change to a Series type which uses the same types of values you can do :

Code: Select all

Private Sub Command1_Click()
  TChart1.ChangeSeriesType 0, scBar
End Sub

Private Sub Form_Load()
With TChart1
    .AddSeries scLine
    .Series(0).FillSampleValues (10)
End With
End Sub
