How to make a surface plot with colors for three variables

5 views (last 30 days)
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')

Show us what you mean with a concrete but smaller data set. Generate a synthetic group of say 4-6 houses and describe using the data for those houses what you're trying to do. It could be that by writing the explanation for the smaller data set you'll answer your own questions (a version of rubber duck debugging that's more like rubber duck designing.) If not seeing the problem described in the concrete rather than the abstract may help us better understand so we can better help you.

Sinmplify your code:
% Replace:
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); % Do you really want a nested cell?
end
% by:
xx = AGG{y};
I = AAI{y};
The actual question is still not getting clear.
