Figure 4-23.
The following example builds a graph in three-dimensional sectors (Figure 4-24 ).
>> x = [1 3 0.5 2.5 2];
explode = [0 1 0 0 0];
pie3(x, explode)
colormap hsv
Figure 4-24.
Then create a tape chart for surface peaks ( Figure 4-25 ).
>> [x, y] = meshgrid(-3:.5:3,-3:.1:3);
z = peaks(x,y);
ribbon(y, z)
colormap hsv
