Horizontal gradient

Dear All,
This is my first post on this forum so apologies if I’m not in the right thread/group.

I’m building a dashboard using widgets and I’m trying to display a temperature feed as a colored gradient.
Basically, I would like my gradient to show from dark blue when temp. are cool to bright red when temp. are getting hot.

The closest widget I see is the “cylinder” where You can set Min/Max values as the bottom/top - however, there is no way to set different colors.

I have also tried with “led” function but this only allows discrete values so not really what I’m looking for…

Is there any widget which would offer this kind of functionality (change color based on value)?
