Do you have a packaged workbook with sample data that we could work with? Or maybe just a mockup of what you're trying to get to?
If you have Pass/Fail already determined in a calculation, you can add those to the color mark and designate what you want to see as red or green. I'm not sure if you can get an additional color in there for samples, but if we can see where you're trying to go with this, then we might be able to help you.
I've attached some mock data and inserted an example of what I'm trying to do.
In addition to the PASS/FAIL color coding, I'm trying to create a set and color those samples a different color. Is that possible?
