hello.
so i used lvgl 8.3 version and created gauges, like this (simple meter) Meter (lv_meter) — LVGL documentation now in 9.2 its impossible for me to create a gauge with adjustable colored zones like measuring temperature. how to do this now? I can create working gauge, but not those colored zones.
Have you looked at lv_scale in version 9.2? There is an example that is similar to what you want to achieve.
Does that not work for you, or have you not seen that as a possibilty? I, too, had to recreate the lost lv_meter from v8.x.x in v9.x.x, and was able to do it with lv_arc and lv_scale
Yes i made perfect gauge using clock example( lv_scale), making tree different colored arcs is pain.
Ok, sooo - did you manage to do it?! Or is something not working? Trying to understand your post so I can offer help, but you need to be more specific about what isn’t working 
It went from ‘impossible’ to ‘a pain’ so I guess progress is being made?!
i said is pain, not was pain haha. ok what i want is add one arc, but this one arc has 3 colours. Like in attachment.

Thanks for help, it worked!
