Threshold Colors

Greetings all,

Having an issue with time series panels using gradient mode: scheme, color scheme: thresholds by value (absolute), hoping someone can confirm these findings.

Using custom RGB color values and anytime the blue value is set to 0 the graph will not render any values that should be that color. As example: rgb(255, 255, 0) fails to render, but changing blue to any non-zero value rgb(255, 255, 1) fixes this issue.

Anyone else able to reproduce this issue? Thanks much!

Below graphs as examples before/after fixing the RGB blue value:

Interesting. I’m having the same issue - grafana Version 10.3.1 (commit: 00a22ff8b28550d593ec369ba3da1b25780f0a4a, branch: HEAD).

I have the same in Grafana v11.4.1 (da7be26d) in a very particular case.
I have a TimeSeries with:

  • Graph styles → Gradient Mode → “Scheme”
  • Standard Options → Color scheme → “From thresholds (by value)”
  • Following thresholds colors → “#FF0000”, “#FFA500”, “#00FF00

I’ve had the same bug for over a year in my temperature graph where one of my overrides drew blank. Thanks to this report I now could fix it by adding 1 to the blue value… or change it to rgba and change opacity. Thanks!
