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!

When the chart category axis is in categorical mode, the actual X values of the categories are 0, 1, 2 etc. That is a const line displayed for the first group must have a value of 0. (assuming you want to display vertical constant lines for specific categories). That is why mapping a certain yyMM value to a category number is not possible via expressions, but is possible with custom code. You can contact Nevron Consulting at contacts@nevronconsulting.com, if you would like them to do this for you.

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.
