The &func &routines analyze either a single-series or a multi-series
scatter chart.
These &routines calculate default values for chart elements without
actually displaying the chart.
.pp
The &func &routine analyzes a single-series scatter chart.
The chart environment structure
.arg env
is filled with default values based on the values
of the
.arg x
and
.arg y
arguments.
The arguments are the same as for the
.kw _pg_chartscatter
&routine..

The &func2 &routine analyzes a multi-series scatter chart.
The chart environment structure
.arg env
is filled with default values based on the values
of the

The &func &routines return zero
if successful; otherwise, a non-zero value is returned.
