As I said in a comment: I could not find a way to do this directly, but I thought I could get around this.
It turns out I was not successful!
But let it cover a boundary case, which for some applications will have a fairly simple solution; let's say you don't need datalabels, unless you want to call:
Sub chartTest() Dim co As ChartObject Dim ch As Chart Dim i As Integer ' The point index we want shown i = 2 Set co = Worksheets(1).ChartObjects(2) Set ch = co.Chart co.Activate ch.SetElement (msoElementDataLabelCallout) For j = 1 To s.Points.Count ' We can change this to an array check if we want several ' but not all points to have callout If j <> i Then s.Points(j).HasDataLabel = False Next j End Sub
For those who despaired, the closest I came to create an overlay was using the original diagram as a template. This does not work exactly for arbitrary diagrams, however due to problems with positioning with the leader field.
But at this point you could just add a text box or something much less active than copying a chart, deleting half of its contents and leaving it invisible ...
But for Ktul's sake, I mean science:
Sub pTest() Dim co As ChartObject Dim ch As Chart Dim s As Series Dim p As Point Set co = Worksheets(1).ChartObjects(1) Set ch = co.Chart Set s = ch.SeriesCollection(1) i = 2 Call copyChartTest(co, ch, i) End Sub Sub copyChartTest(ByRef co As ChartObject, ByRef cht As Chart, ByVal i As Integer) Dim ch As Chart ' The overlay chart Set ch = co.Duplicate.Chart ' Set callout ch.SetElement (msoElementDataLabelCallout) ' Invisibil-ate! With ch .ChartArea.Fill.Visible = msoFalse .SeriesCollection(1).Format.Line.Visible = False .ChartTitle.Delete .Legend.Delete For j = 1 To .SeriesCollection(1).Points.Count .SeriesCollection(1).Points(j).Format.Fill.Visible = msoFalse If j <> i Then .SeriesCollection(1).Points(j).HasDataLabel = False Next j End With ' Align the charts With ch .Parent.Top = cht.Parent.Top .Parent.Left = cht.Parent.Left End With End Sub
And the result: DataLabels is intact, with only 1 point having a leader.
