I am sorry, I did not understand the advice. I’ve set up a MWE which I should have done so already in my first post:
using CairoMakie
x = 1:10
y = 1:10
c = rand(10,10)
cmap = :delta
fig, ax, hm = heatmap(x, y, c; colormap = cmap)
cb = Colorbar(fig[1,2], hm)
fig
what I want to achieve is that the “blue” part of the color map covers the range (e.g.,) 0-0.25, and the “green” part covers the range 0.25-1.0, instead of the currently symmetric case of covering each 50-50. I want to be able to utlize all colors in the color map, not cut off e.g., the bottom deep blue color.
