How can you determine which legend item has been clicked

[AR]

I have a legend on a chart with checkboxes. I have been looking through the ChartEvents but cant seem to find one that is fired when the checkbox for a series is changed, does such an event occur ?

Hi AR,

Yes, you can use OnClickLegend event and the legend clicked event to obtain the clicked item index as shown here:

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)
    TChart1.Header.Text.Clear
    TChart1.Header.Text.Add (CStr(TChart1.Legend.Clicked(X, Y)))
End Sub

Thanks that worked, I had found that event and dismissed it as it didnt provide a series index.

Hi AR,

I'm glad to hear that did what you needed. Clicked method can be used to retrieve series points index in events where screen coordinates are provided.
