Colorbar Span / Custom tick

Community Support

Hello everyone.

I’m trying to add (and style → change color and size) a line to a specific location in a Colorbar.

Given a slightly modified version of the unemployment heatmap example available in a gist here, I would like to map the US colorbar (palette: blue to salmon) into the World colorbar (palette: white to blue).
To achieve that I think the best option is to add a line (span?) in the World colorbar at locations 3, minimum of US colorbar and 11.4, maximum of US colorbar (like shown below).

How can one do that?

Thanks

There is not currently any capability for this, but it seems like a reasonable ask, and it may become easier to implement after some current ongoing improvements to colorbars are finished. Please feel free to open a Github issue to request this feature.
