Dear Friends
I would like to plot the figure with 3 variables in 2d, with the value of z is proportional to the color as the figure attached. where X(1 x N); Y(1 x N) and Z(N*N) matrix. I want to have a scatter plot as an attached figure. Thank you for your attention
Code
load('w.mat');load('k.mat');load('Detal_E.mat');
w0=6.266963343377698e+05;
[X,Y] = meshgrid(w/w0,k);
h=surf(X, Y,Detal_E*1e6);
xlabel('w')
ylabel(' k')
zlabel('Detal E')
myColorMap = jet(250);
myColorMap(1,:) = 1;
colormap(myColorMap);
colorbar
shading interp;
view(2)

m=min(Detal_E);
M=max(Detal_E);
c=(Detal_E-m)/(M-m)*9+1;
scatter(X,Y,25,c,'filled');
