ERRORBAR

        [GREG1\]ERRORBAR Argument [Array_X Array_Y Array_Z [Orientation]]

    This  command draws error bars on all (X,Y) points (read by COLUMN X and
    Y, or specified in Array_X Array_Y) of length read by COLUMN Z or speci-
    fied  by Array_Z.  Argument may be +X X -X +Y Y or -Y.  Symmetric error-
    bars are drawn if you do not specify the sign, while only  the  errorbar
    of  the given sign is drawn if you do so. This allows independent error-
    bars in opposite directions. The size of the line at the end of the  er-
    rorbar is the Marker size and can therefore be adjusted with SET MARKER.

    Errorbars  with arbitrary orientation can be obtained by specifying code
    +O, O or -O. The orientation (in degrees) is then  either  read  from  a
    fourth array if one is specified on the command line, or otherwise taken
    from the current marker orientation (as specified in SET ORIENTATION).
