How to Create Different Reference Line for each column in column chart
Hi,
I am trying to create a column chart that shows the average test score for each grade level. However, each grade level also has a national norm to compare the average against. I would like each column to have a reference line representing the national norm for that grade level in each bar (to look like the attached image--this chat was created in Tableau and I'm trying to recreate in PowerBI). I have the norms as a separate data source from the test score data, and they have a 1:m relationship between the norms data and test score data. However, in the analysis pane of PowerBI, I can only see how to add in a single constant line, rather than have the line be different for each column. Is there a way to do this in PowerBI?

you can do a combined column and line chart, and draw only the line markers but not the line itself.
