I’m trying to efficiently create visualizations of a 2D Ising model (i.e., see Ising model - Wikipedia ). Using Julia plots contour seems wasteful, and is definitely slow. Is there some simple black/white plot that could be used?

heatmap ? heatmap(rand(0:1, 500,500), c=cgrad([:black, :white])) [image]

Efficient Black/White Colormap plot
