Checkbox for a series group

[JAV]

It is possible to group several series in a single checkbox under a main serie, so that the checkbox in the main serie will serve to display or hide the whole group while each sub series could be controlled with their own individual checkbox?

For example, the image attached shows four series where T-A6:M1 is the main serie. The idea is that T-A6:M1 checkbox turns on and off the others and, at the same time, P10, p50 and p90 must keep their checkboxes working.

Hello JAV,

You could use OnClickLegend to control how the other series must respond when a concrete area is clicked (the area for the main series item).
Here it is an example:

Code: Select all

Private Sub Form_Load()  
  TChart1.Aspect.View3D = False
  
  Dim i As Integer
  For i = 0 To 3
    TChart1.AddSeries scFastLine
    TChart1.Series(i).FillSampleValues
  Next i
  
  TChart1.Series(0).Title = "Main series"
  TChart1.Series(0).Pen.Width = 3
  
  TChart1.Legend.CheckBoxes = True
End Sub

Private Sub TChart1_OnClickLegend(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  If ((X >= TChart1.Legend.Left) And (Y >= TChart1.Legend.Top) And (X <= TChart1.Legend.Left + TChart1.Legend.Width) And (Y <= TChart1.Legend.Top + TChart1.Canvas.FontHeight + 5)) Then
    Dim i As Integer
    For i = 1 To TChart1.SeriesCount - 1
      TChart1.Series(i).Active = TChart1.Series(0).Active
    Next i
  End If
End Sub

This sets the "other series" to be active if the main series is set to active, and sets the "other series" to be hidden if the main series is hidden. If you want to remember the "other series" statuses before they are set to be hidden, you could use variables to do so.
