# How to make a surface plot with colors for three variables

I want to plot how the increase in power demand AAG of households relates to the number of inhabitants AAI. I have 36 houses and investigates the increase for the combinations of 1,2,3...36 houses (y)

I have tried making plots, but the only thing I can come up with is scatter plots, but then the number of households. Since I combine 2,3,4... 36 households I will have 36 scatter plots if I do like this

but I want one 2D surface plot with colors. Inserted the data for 1 and 2 households to make things more clear.

for y=1:2

xx=cell(length(AAG{y}),1);

I=cell(length(AAG{y}),1);

for o=1:length(AAG{y})

xx{o} =AAG{y}{o};

I{o}=AAI{y}(o);

end

for k1 = 1:length(AAG{y})

scatter(ones(1,numel(xx{k1}))*y, xx{k1},ones(1,numel(xx{k1}))*I{k1},'s','Linewidth',10)

end

end

colormap(parula(100));

colorbar;

h=colorbar;

ylabel(h, 'Number of inhabitants')

caxis([2 10])

ylim([0 20])

xlim([0 3])

xlabel('Nr of households being combined')

ylabel('Increase in rated power')
