kenzieschmoll commented 4 years ago

Terry, does this look like it was coming from the old timeline frames chart? bar_line_chart_painter seems like it may have, but I'm not sure if that is used in the memory chart as well. If this was from the old timeline chart, we can close this issue

terrylucas commented 4 years ago

Closed Timeline doesn't use MPChart but also fixed in a previous PR for other MPChart usage.
