The best way forwards I think is to make a Pull Request at InteractiveDynamics.jl that allows this heatmap out of the box. Makie.jl supports a heatmap with arbitrary coordinates. So first one makes the coordinates, nbinx, nbiny = size(property) . Then coordx = range(0, 1; length = nbinx) and same for y . Then, heatmap!(ax, coordx, coordy, property; ...) . Shouldn’t be too hard.
