I created a simple chart based on a data source with a calendar year characteristic (0CALYEAR) in the columns and a keyfigure (amount) in the rows. It seems like Design Studio wants to display the label values of the years as numerical values. That wouldn't be such a problem, but Design Studio also adds a thousands separator! So 2013 becomes 2.013. The mouseover on the other hand displays the value in the correct way. Check the screenshot.
I searched for a CSS property to fix this, but apparently this isn't possible with CSS. Am I overlooking something and is there a fix/setting for this?
