I want a bar chart with gap zero.
When I set gap width to zero and the border of the bar to single line, then
the border between two bars is shown as double. I don't like the visual
appearance of this.
I am rewriting a word-app to an excel app and the point is that the same
barchart is shown in Word with a single line between to charts (that means
that the borders of two adjacing bars overlap each other. I want the same
behaviour in Excel but I don't get it. Why this inconsistency? Is there a
workaround?
