[x,y] = meshgrid(linspace(-3,3));
z = exp(-x.^2 - y.^2);
H = pcolor(z);
H.LineStyle = 'none';
colormap(jet)
axis equal
Lots of variations on this theme. Be creative.

pcolor produces a colored surface, at a default height of z==0.
You can add additional information to a figure if you use the hold command, and then issue additional information to the figure.
You can control various aspects of what you see, what is labeled (as you should know) by use of the graphics handles as returned from the various tools used to create what you plotted.
