Hi there,

I have this figure that you can see in the picture. Is it possible to change the coloring in the legend so that you can see the difference between the two like in the picture?

Thanks.

Share the code, which has bben used to generate this plot.

The last part, but I copied the data as well.

mu = [25 45];
sigma = [20 10; 10 50];
x1 = 0:1:50;
x2 = 0:1:180;
[X1,X2] = meshgrid(x1,x2);
X = [X1(:) X2(:)];
y = mvnpdf(X,mu,sigma);
y = reshape(y,length(x2),length(x1));
mu_jugo = [10 130];
sigma_jugo= [15 5; 5 30];
y_jugo = mvnpdf(X,mu_jugo,sigma_jugo);
y_jugo = reshape(y_jugo,length(x2),length(x1));
%3D 
figure
surf(X1, X2,y)
set(gca,'FontName','Times','FontSize',12)
hold on
surf(X1, X2,y_jugo)
set(gca,'FontName','Times','FontSize',12)
legend({'Bura','Jugo'},'FontName','Times','FontSize',12)
colormap(jet)

@Frane Choose the color as you want to distinguish between multiple surf plots.

See the colormap also

Hello there,

I just wanted to ask you again on this question beacuse I have to use this figure in X-Y view as well. The first image shows what I've done in the beggining and the other one shows yours. You did what I asked you guys to do and that is to change the color of the legend but as you can see I can't use like this because the area in the X-Y view has to be like the first one.
