Hi Yusuf and Gysbert!
Thank you both for your fast reply!
I first tested unchecking "Size to Data", but that didn't help.
Then I disabled the legend and labels. That seems to solve the problem, but I would like to have labels showing the numbers. I see that the chart with less digits in the labels become larger. I suppose the size of the labels use some of the chart size (in a way).
Do you have any suggestions for showing labels in another way?
