I need a reference line on my Trellis chart to mark a threshold. As suggested in the discussion board. I added the value in the reference line in the presentation setting. The line is not showing up. Is there some setting I need to check?
I just tried with a bar chart and a simple constant value as expression for the reference line, and it did show up.
What type of chart are you using? If you disable the trellis chart, does the line show up then?
