I have a Trend Graph that uses Filter Pull Downs here: https://metabase.sophos-tools.com/question/536?trend_suite=Mobile%20Suite
The problem I am having is that even though I have set the colors to Green = Pass, Red = Fail, Gray = Skip there are times the graph gets drawn where the colors for Pass and Fail switch. This causes some confusion to my Users who though they see a test with a high Pass rate that rate is displayed on the graph in Red, which most think of as a Fail. This happens when people use the URL link back to the report, we have some static URLs setup on an internal page that allow review of the trend with a specific filter value already set.
Is there some reason that a Trend Report would switch colors that are set in the original question? If say the counts for Fail were higher than Pass it now takes a color assigned to another value for display.
