How to draw a pie chart in Matlab

You can use the pix function in Matlab to create a pie chart. The Calling format of the pie function is as follows:
Pie (X)
Use the data in X to draw a pie chart. Each element in X is represented by a slice area in the pie chart.
Pix (X, eplode)
Separate a slice area from the pie chart. The explode is a zero or non-zero matrix corresponding to X. The Slice corresponding to the non-zero value is separated from the pie chart. Therefore, if explode (I, j) is not zero, the slice corresponding to X (I, j) is separated from the center. Exploade must have the same size as X.
H = pie (...)
Returns the handle vector to the shadow and Text Graphics objects.
