Three-dimensional pie and bar:
For the bar3 function, x & y vectors are passed and the function displays three-dimensional bars as shown in figure:
Figure: Three-dimensional bar chart.
>> x = 1:6;
>> y = [33 11 5 9 22 30];
>> bar3(x,y)
Likewise, the pie3 function display data from a vector as a three-dimensional pie as shown in Figure
>> pie3([3 10 5 2])
