{title:Description}

{pstd}
{cmd:twoway pcscatter} draws markers for each point designated by 
({it:y1var}, {it:x1var}) and for each point designated by 
({it:y2var}, {it:x2var}).


{title:Options}

{phang}
{it:marker_options}
    specify how the markers look, including
    shape, size, color, and outline;
    see {it:{help marker_options}}.  The same marker is used for both sets of
    points.

{phang}
{it:marker_label_options}
    specify if and how the markers are to be labeled; 
    see {it:{help marker_label_options}}.

{title:Remarks}

{pstd}
Visually, there is no difference between

	{cmd:. twoway pcscatter} {it:y1var} {it:x1var} {it:y2var} {it:x2var}

{pstd}
and

	{cmd:. twoway scatter} {it:y1var} {it:x1var} {cmd:||} {...}
{cmd:scatter} {it:y2var} {it:x2var}{cmd:, pstyle(p1)}

{pstd}
though in some cases the former is more convenient and better represents the
conceptual structure of the data.

{pstd}
Note that the two scatters are presented in the same overall style,
meaning that the markers (symbol shape and color)
are the same.
