MATLAB also has plotting functions for three-dimensional data. Many of these functions have names similar to their two-dimensional versions, but with a 3 at the end.

% using bar3 function
x = 1:6;
y = [33 11 5 9 22 30];
subplot(1,3,2)
bar3(x, y);

% using pie3 function
subplot(1,3,3)
pie3([3 10 5 2])
title('3D pie chart')
Solution
A 3D plot uses x, y, and z coordinates. This can be helpful when each data point has three related values.
