+## Called with a single vector argument, produces a 3D pie chart of the
+## elements in @var{x}, with the size of the slice determined by percentage
+## size of the values of @var{x}.
+##
+## The variable @var{explode} is a vector of the same length as @var{x} that
+## if non zero 'explodes' the slice from the pie chart.
+##
+## 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} provides a handle list to patch, surface
+## and text objects generating this plot.
