Excel VBA Line Color / Marker Line Color

Question

I\'m writing some VBA code to modify Excel charts. For a scatter chart I need to modify the marker line colour and sometimes the line colour of the connecting lines. I can d

Answer 1

The line colour of the connecting lines is Series.Format.Line.ForeColor. The marker line colour is Series.MarkerForegroundColor. But at least with Excel 2007 there is a problem with setting Series.Format.Line.ForeColor. See example:

Sub Macro3()
 Dim oChart As Chart
 Dim oSeries As Series

 Set oChart = ActiveChart
 Set oSeries = oChart.SeriesCollection(2)

 oSeries.Format.Line.Weight = 5 'Line.Weigth works ever

 oSeries.Format.Line.Visible = msoFalse 'for Line.ForeColor getting to work we have to cheat something
 oSeries.Format.Line.Visible = msoTrue
 oSeries.Format.Line.ForeColor.RGB = RGB(0, 255, 0) 'now it works

 oSeries.MarkerSize = 15
 oSeries.MarkerBackgroundColor = RGB(255, 0, 0) 'marker background

 oSeries.MarkerForegroundColor = RGB(0, 0, 255) 'marker foreground (lines around)
End Sub

The ActiveChart is a scatter chart. And this is tested with Excel 2007.
