As far as I know, you can only use the inbuilt reference line function when your x axis is continuous.
Go to Axes and on the bottom half of the options, tick continuous for your axis (assuming you want it to be..!)
Then in the Presentation tab you can choose reference line, add one on the Continuous X Axis and give it an expression like =5 for example, which on a continuous scale from 1-20 would create a reference line at 5.
vertical reference lines are only available for continuous dimension axes, so you have to set your dimension axis properties accordingly:
hope this helps
Thank you so much for the help. But I can't make my dimension axis continuous as I'm representing dates as my dimension which are take from an excel sheet and are not continuous.
Is it still possible to define some vertical reference lines at some of the selected dates?
Thanks and Regards
I need same in Qliksense, Do we have any work around to check? If possible, Can you share V1 in sense (QVF).
