I did find that and I don't think it will solve the problem I have, which I should have stated š¬
We have a list insight. It has data has counts and a score. Image below (forgive my art skills). That Trend column. I want to add that, with a custom graphic to indicate the trend. We use dashboards almost exclusively. We do not want to move away from dashboards. We are relying on their built-in functionality to deliver consistent experiences.
While we could do this with a custom visualization as noted in that link, we wouldn't be able to get that visualization on to a dashboard, to the best of my knowledge. We could try a dashboard plugin but that path has been explored with Professional Services and the conclusion indicated it was not in the cards at this time.
I could have sworn while I was looking through all the documentation around dashboard plugins I ran across some information about custom renderer. That would allow you to take in an insight and modify it. However, I cannot seem to locate that information now.
Is there a way to do what I've indicated in this image using dashboards?
