Is there a canonical way for domain colour plots in Makie? I tried using Image, but it doesn’t have an option for me to specify the axes. heatmap! doesn’t seem to work for complex numbers either.

I found a way that works with heatmap. The trick is to use a function that can output colour directly. heatmap doesn’t like functions that output complex numbers. using Colors function domain_color(z::Complex)::HSL luminance = (atan(log(abs(z) ^ 0.6)) + pi/2) / pi hue = angle(z) / pi * 180…
