I am not certain what you want.
Hereare two options, the first simply a ‘patchwork’ plane, and the second a 3D bar3 plot:
M = randi([0 1], 7); % Create Matrix
cmap = [1 0 0; 0 0 1]; % Define Red-Blue ‘colormap’
figure
imagesc(M)
colormap(flipud(cmap))
figure
h = bar3(M);
colormap(cmap)
for k1 = 1:numel(h)
q = h(k1).ZData;
h(k1).CData = ones(size(q)).*(q==0);
h(k1).EdgeColor = [1 1 1]*0.8;
h(k1).CData(:,1) = 0;
end
axis equal
You will likely need to experiment to get the result you want with your data.
