Hello,

I have to make a plot depending on 2 angles and a radius. so long there is no problem. Is ist possible to make the color of the plot according to the radius and not to the z-axis lie it is usually?

my code:

Code:

clear all;
load data2;
phi=data2(:,2);
theta=data2(:,1);
radius=data2(:,3);
[hor vert]=meshgrid(0:360,0:360);
r=griddata(theta,phi,radius,hor,vert);
[x y z]=sph2cart(hor*pi/180,vert*pi/180,r);
surf(x,y,z);
colorbar;
axis auto
hold on


thanks for all answers!

greez

Take a look at the first two paragraphs in the M-file help for the SURF
function, then try:


surf(x, y, z, x) % using the x, y, and z variables from your original code


Then generalize.
