Removing a Piece from a Pie Chart

When the sum of the elements in the first input argument is equal to or greater than 1, pie and pie3 normalize the values. So, given a vector of elements x, each slice has an area of x_i/sum(x_i), where x_i is an element of x. The normalized value specifies the fractional part of each pie slice.

When the sum of the elements in the first input argument is less than 1, pie and pie3 do not normalize the elements of vector x. They draw a partial pie. For example,

• x = [.19 .22 .41];
  pie(x)
