Hi,
Create your stacked column chart using all the data.
Select the series that contains the average data. Change the series chart
type to Line.
Cheers

I want to combine a standard stacked column chart with a line that, for
example, presents the average value of stacks in each column. This is only
possible by drawing manually a line in the stacked column chart, or is
there
a better trick?
