Partial transparent surface plot

61 views (last 30 days)
Hello together,
I'm trying to plot a surface where all points with a z value between -0.5 and 0.5 are 100% transperent. I've tried to make all these values to NaN (not a number). This works, so far, that the surface looks like expected, but i can not use the data cursor. When using the data cursor matlab crashes. Is there another way of makeing areas transparent or does anyone know, why matlab crashes?
Thank you for your help.
Rafael

You can set AlphaData to 0 where you don't want to see any colour. Here is an example hiding values of a trigonometric function between 0 and 1:
[X,Y] = meshgrid(1:0.5:10,1:20);
Z = sin(X) + cos(Y);
s = surf(X,Y,Z);
s.AlphaData = (Z<=0) | (Z>=1);
s.FaceColor = 'texturemap';
s.FaceAlpha = 'texturemap';

Are you just visualizing the image or trying to print it using print? Please, post some of your code.
By the way, from the help page Figure Properties I see z-buffer is no longer supported:
Note: The 'zbuffer' option has been removed. Use 'opengl' or 'painters' instead.
What Matlab version are you using?
