MATLAB: Create area at z-axis

Question

In MATLAB, the area-function can be used to created a shaded area from data. For example: area([xmin xmax],[ymin ymax]) This are is drawn at the z-axis z= 0. How can I make a shaded area plot at a certain z-distance (so basically just a slice)?

Answer 1

You can use the patch of fill3 functions:

Simple example:

X = [0 1 1 0];
Y = [0 0 1 1];
Z = [0.5 0.5 0.5 .5];
fill3(X,Y,Z,'g')

in which you play with the z coordinate. Is that what you meant?
