.desc begin
The &func &routines display either a single-series or a multi-series
scatter chart.
The chart is displayed using the options specified in the
.arg env
argument.
.pp
The &func &routine displays a scatter chart from the single series
of data contained in the arrays
.arg x
and
.arg y.
The argument
.arg n
specifies the number of values to chart.
.pp
The &func2 &routine displays a multi-series scatter chart.
The argument
.arg nseries
specifies the number of series of data to chart.
The arguments
.arg x
and
.arg y
are assumed to be two-dimensional arrays defined as follows:
.millust begin
.if '&lang' eq 'C' .do begin
float x[ nseries ][ dim ];
.do end
.el .do begin
real x( nseries, dim )
.do end
.millust end
.pp
The number of values used from each series is given by the argument
.arg n,
where
.arg n
is less than or equal to
.arg dim.
The argument
.arg labels
is an array of &strings..
These strings describe each of the series and are used in the chart legend.
.desc end
.return begin
The &func &routines return zero
if successful; otherwise, a non-zero value is returned.
