PLOT <data>,<xvar>,<yvar> 
where <xvar> and <yvar> are names of the variables in the data file.
plots a scatter diagram or a time series.

The character indicating the place of each observation may be given by a
POINT=<character> specification. If POINT is omitted, a small point is
plotted. Also values of a third variable may be plotted by using
POINT=<name of variable>.

To make a line graph (plot of time series) a LINE specification has to
be included. It has the form LINE=<line type>,<thickness>,<line label>,
see LINE.
In time series plotting <xvar> may be replaced by TIME(<xvar>). Then
the points on the X scale will be notated by the values of <xvar>.
For example, in plotting a monthly time series SER12 in data DATA3 and
using variable YEAR for X scale notations
PLOT DATA3,TIME(YEAR),SER12  / XSCALE=1(12)61 GRID=XY TICK=1
produces a graph where years are notated with labels and months with
small ticks.

PLOT <data>,<xvar>,<yvar1>,<yvar2>,...
plots simultaneusly (at most 12) variables <yvar1>,<yvar2>,,,
against one <xvar>.
The consecutive points of each <yvar> are connected by a line specified
by LINE. Each <yvar> can have a line type of its own by giving specifi-
cations of the form
   <yvar>LINE=<line type>,<thickness>,<line label>    (see LINE).
The consecutive points of each <yvar> are labelled by the POINT specifi-
cation. Each <yvar> can have a label of its own by giving specifications
of the form
   <yvar>POINT=<list of parameters according to POINT>   (see POINT).
