Thank you,
I tried it but it didn't work,
however, I have searched this a bit again and now I found something that works - thanks to these guys (link1, link2 and link3):
ActiveChart.SeriesCollection(14).Select
With Selection
.Border.LineStyle = xlContinuous
.Border.Color = RGB(255, 0, 0) 'Gives only the line (also called border) a colour
.Border.ColorIndex = -4142 ' Makes the line disappear (Note that this needs "Colorindex" not Color - It's a "discrepancy")
.MarkerBackgroundColor = RGB(255, 255, 255) '-2
.MarkerForegroundColor = RGB(0, 0, 255) '-2
End with
The to latter lines gives colours to the fill and the border of the marker and the input "-2" (instead of some RGB-code) makes them dissappear too.
Now a second problem, if I want to edit the marker border size, it's a bit cumbersome:
.Format.Line.Weight
will change both line and marker border.
However it is possible to then change the line only (border only):
.Border.Weight 'But this works strangely with the input - Found at (link4)
I haven't found a similar property only for the marker border.
