When combining scalebreaks and series stacking, the rendered chart does not match the data. See attached solution: The bar of the category "1/2016" has a length of 105 (as indicated by the tooltips) -- but the corresponding axis labeling shows a value of 37. The scalebreak is off too (probably matching the wrong axis).
Thank you for your input Andreas. Currently, scale breaks are not supported in Stack and Stack100 modes. I have edited this item title, so it will be a feature request for such functionality and people can vote for it using the Like button and also share their comments.
