Often times, lines overlap one another, and I can’t hover over the line I’m interested in to see the data that hides underneath (e.g. how many passed test cases on a given day).
Thanks for your feedback! That’s currently not possible unfortunately but I’m happy to add this to our list of things to look into. As mentioned in the other thread, it would be possible to use TestRail’s XML/CSV exports to generate custom reports outside of TestRail and this may make sense if you prefer a different chart layout (bar instead of line chart, different date ranges, etc.):
