How detect when series checkbox is selected in the legend?

[Dave]

Hi

To display the checkboxes beside each series in the legend i do this;

theChart.Legend.CheckBoxes = true;


If the user selects a checkbox how do I detect this??

Thanks!

Hello,

You can use the OnClickLegend event as follows:

Code: Select all

Private Sub TChart1_OnClickLegend(ByVal Button As TeeChart.EMouseButton, ByVal Shift As TeeChart.EShiftState, ByVal X As Long, ByVal Y As Long)
  Dim i As Integer
  Dim tmpX As Integer
  Dim tmpY As Integer
  If TChart1.Legend.CheckBoxes Then
    tmpX = TChart1.Legend.Left + 5
    For i = 0 To TChart1.SeriesCount - 1
      tmpY = TChart1.Legend.Item(i).Top + 2
      If (X >= tmpX) And (X <= tmpX + 10) And (Y >= tmpY) And (Y <= tmpY + 10) Then
        MsgBox "Checkbox for Series " + Str$(i) + " clicked"
      End If
    Next i
  End If
End Sub

Thanks Yeray. But unless Im mistake this code does not show whether a box is selected or deselected?

BTW. I meant to post this question on the .NET thread. So I will post there and link to your reply.
