POINT=<character or name of a variable> 
(in PLOT operation for scatter diagrams and time series)
specifies the label to be plotted for each observation in the graph.
In case of <name of variable> the values of that variable will be
plotted so that the center of the first character indicates the position
of the observation.
If POINT is omitted, a small dot or circle is plotted for each observation.

Another form of the POINT specification is
POINT=<marker_type>,<marker_size>       or
permitting symbols of various sizes depending on the value of the
marker variable.
The possible values of <marker_type> are 0,1,2,... and their interpre-
tation depends on the plotting device. A table of types is given
on the next page.

The size of the symbol in the general case is

If <max_value>=0, the values of <marker_variable> will be used as
<marker_type> values. Thus different observations may have different
This can also be done by a POINT_TYPE specification (see POINTT?).

The color of the marker can be specified individually for each
observation (see POINTC?).

Possible Survo marker types on different devices:

         Screen          PostScript
 0       filled circle   same
 1       plus            same
 2       asterisk        same
 3       circle          same
 4       cross           same
 5       square          same
 6       filled square   same
 7       triangle        same
 8       filled triangle same
 9       diamond         same
10       filled diamond  same
11       pixel           -
21       -               arrow         ARROWLEN=integer specifies arrow length
22       -               filled arrow           as coefficient of marker size

default  circle          circle
   size  2               5

In Survo PostScript graphics, POINT=any,0 draws a marker defined
by the PostScript function `dot'. This function is readily defined in
PS.DEV as a tiny dot and may be altered by the user.

In point types 21,22 (arrows) the direction of the arrow is given
in POINT specification of the form POINT=...[rotate(var)]...
where a variable 'var' gives the rotation angle in degrees.
