Creating colormap at specific point and color weights at matlab

Question

i have some datas which are included some deflection and force values. Like deltaX deltaY and forces measured at that points as Fx and Fy. I want to create a colormap at that po

Answer 1

You can use meshgrid and surf or mesh command to plot it:

[X,Y] = meshgrid(filein(:,1),filein(:,2));
M = sqrt(filein(:,3).^2+filein(:,4).^2);
Z=meshgrid(M,M);
C = gradient(Z);
figure
surf(X,Y,Z,C);colorbar

You can remove the mesh and interpolate as follows:

surf(X, Y, Z,'EdgeColor', 'None', 'facecolor', 'interp');

Then view it from above:
