I’m not certain exactly what you are describing. QS has a concept of reference lines, which can be dashed line running across a bar chart (in our case). It’s available from the “format visual” command.
In the visual above the 321 is the value of the reference line. This value varies depending on the how the filters are set (such as the property control).
Hi, @shalakam. Did @cgreenacre’s solution work for you? I am marking their reply as, “Solution,” but let us know if this is not resolved. Thanks for posting your questions on the QuickSight Community Q&A Forum!
