I have the following function, that I use to plot two iso-surfaces from data collected in CFD. The only problem is that it does not plot both colors, only gray. This works perfectly in newer versions of MatLab so my guess is that that is the main problem.

Here is my function.

function [ p ] = draw_isosurface(xBox,yBox,zBox,component,iso_plus,iso_minus,plus_color,minus_color)
%Draw 2 isosurfaces about the input values in the same figure
% <Input>
% xBox, yBox, zBox: X,Y,Z in 3D
% component: The thing you want to look at
% iso_plus, iso_minus: Positive and Negative value of iso-value.
% plus_color, minus_color: Name of the color or RGB code of isosurfaces 
p=patch(isosurface(xBox,yBox,zBox,squeeze(component),iso_plus));
p.FaceColor = plus_color; p.EdgeColor = 'none';
alpha(.5)
camlight 
lighting gouraud
hold on
p=patch(isosurface(xBox,yBox,zBox,squeeze(component),iso_minus));
p.FaceColor = minus_color;
p.EdgeColor = 'none';
alpha(.5)
camlight
lighting gouraud
grid on
axis equal
end
