In this viz I am using a bar chart as a filter for other worksheets on the same dashboard. I have selected the year 2017, and you can see that the background behind the text "2017" is colored differently. Which property should I modify to change this color? I am unable to figure out.
Try editing the Action (Dashboard >> Actions), and make sure that the source worksheet is not also selected as a target. I believe if you remove that selection, it will no longer highlight itself or dim the other marks. Let me know if that makes sense or works for you at all! Happy analyzing.
