Hello,

My primary X Axes is grouped by following statement: =FORMAT(Fields!ESA_IVRProcessEnd,"yyMM").

How can I set a const line on a specific yyMM value? Is that possible?

Thank you for your help!

Thanks. That helps. I can work with the numbers since I always have the same amount of month on the x axes.

I noticed that it is also possible to use for example 5,5 as value to set the line between tick marks.
