    20## @deftypefn {Function File} {@var{h} =} stem3 (@var{x}, @var{y}, @var{z}, @var{linespec})

    21## Plot a three-dimensional stem graph and return the handles of the line

    22## and marker objects used to draw the stems as "stem series" object.

    23## The default color is @code{"r"} (red).  The default line style is

    24## @code{"-"} and the default marker is @code{"o"}.

    25##

    26## For example,

    27## @example

    28## @group

    29## theta = 0:0.2:6; 

    30## stem3 (cos (theta), sin (theta), theta) 

    31## @end group

    32## @end example

    33##

    34## @noindent

    35## plots 31 stems with heights from 0 to 6 lying on a circle.  Color 

    36## definitions with rgb-triples are not valid!

    37## @seealso{bar, barh, stem, plot}

    38## @end deftypefn
