MATLAB: Transparent and Multi-Color 3D-Surfaces

mesh plottransparency

Hello Community,
I've got a problem with coloring two mesh-plots. The upper one should be sort of transparent, so that the plot below is also visible. I've already tried to apply the alpha-function with a very low value, but I cannot see a significant change in the transparency of the first mesh plot.
Here is my code:
figure
hold on
s1 = mesh(radius_interp, force_interp, bow_length);
alpha(s1,0.01)
colormap(jet)
freezeColors
s2 = mesh(radius_interp, force_interp, bow_length_tape, 'FaceAlpha', 0.8);
map = [0.3, 0, 0
0.4, 0, 0
0.5, 0, 0
0.6, 0, 0
0.8, 0, 0
1.0, 0, 0];
colormap(map)
freezeColors
% Plot Axis
axis([0 200 0 500 0 70])
daspect([1 1 1])
Thanks in advance for your help! Georg

  • This is a guess since I cannot run your code.
    See if decreasing the 'EdgeAlpha' property (especially in a mesh plot) helps.
