+## The variable @var{explode} is a vector of the same length as @var{x} that

+##
+## If given @var{labels} is a cell array of strings of the same length as
+## @var{x}, giving the labels of each of the slices of the pie chart.
+##
+## The optional return value @var{h} is a list of graphics handles to the patch,
