I'm trying to create a radial gauge (or marker or filler I suppose) where the high values are green instead of red (i.e. service availability). I tried something as simple as "gauge successRate 100 99 95" and that did now work. Is this not possible? I'm still running 4.2.2 and yes, I know I should upgrade.
So I didn't see this in plain text, but I did get the gist of your answer from your post. The answer is, change the order of the gaugeColors option around making red first, yellow, then green. I now have a dial showing my service availabiltiy where 4 9's is green as it should be.
