POINTS

        [GREG1\]POINTS [Array_X Array_Y] [/BLANKING Bval Eval] [/SIZE Z_Val-
    ue [Array_Z [Exponent]]] [/MARKER Array_Nsides Array_Style]

    Makes  points  of  the current style (MARKER), size (MARKER and EXPAND),
    and orientation (ORIENTATION) at the coordinates read by COLUMN,  or  in
    the variables Array_X Array_Y.

    With  the  option  /SIZE,  followed by a real value Z_Value, POINTS will
    draw markers of sizes governed by the values of the Z array (or  of  the
    array  Array_Z  if specified). Points with Z value equal to Z_Value will
    have a marker of size the current marker size.  All other  markers  will
    have  an AREA proportional to the Z value at each point (i.e. marker ra-
    dius at X(i) Y(i) proportional to the square root of  Z(i);  this  power
    law  exponent can be changed by specifying an additional argument to op-
    tion /SIZE).  If Z_Value is equal to zero, the program uses the  maximum
    absolute value of the Z array instead.

    The  /BLANKING  option  can be used to override the current blanking be-
    haviour, as defined by SET BLANKING command.

    The /MARKER option can be used to specify a different  marker  sidedness
    and style for each data point.
