MATLAB Pie()

This function creates a pie plot. This function determines the percentage of the total pie corresponding to each value of x, and plots pie slices of that size.

The optional array explodes controls whether or not individual pie slices are separated from the remainder of the pie.

Syntax

pie(x) // It draws a pie chart with the data in x.
pie(x, explode) // It offsets a slice from the pie.explode is a vector or matrix of zeroes and non-zeroes corresponding to x.

Example

World population by continents.
cont= char('Asia','Europe','Africa',....'N.America','S.America');
pop=[3332;696;694;437;307];
pie(pop)
for i=1:5,
	gtext (cont(i,:));
end
