           plot type

           group    - (optional) Define the data group to plot.
                      Default is current group. Must be in
                      range [0..29].

           data     - plots the data of group given . X/Y ranges are
                      kept. Undefined points are plot but not
                      connected. Error bars also
                      will be drawn if not inhibited (s.b.).

           Apart from IDL oplot keywords following special
                      are defined:
           noerror  - Do not plot error bars. This is useful for
                      tight data sets.
       undefined    - Plot undefined data points. Useful for
                      closer inspection.
           noselect - Do not mark selected data points. Useful for
                      final plot.
           norange  - Do not compute range (auxiliary data). Should
                      not be used if single plot type.
           gaps     - Do not connect datapoints which are gaps in
                      respect of a regular x base. It is assumed that
                      the periodicity is defined by x[1] - x[0].
           gaptol   - Defines above which x difference gaps are
                      recognized. Must be given in units of binning
                      width=x[1] - x[0]. Default is 0.1 = 10%.
           distinct - Plot each subgroup file with a different
                      color.
           xbin     - Plot bin width of each data point. If no dx
                      column is given the half distance between two
                      data points is used.
     witherrorrange - Include error ranges into range determination.
        selectcolor - Color for selected data points.
        undefcolor  - Color for undefined data points.
        deltacolor  - Color difference for distinct data sets.
     deltalinestyle - Increase of line styles for distinct data
                      sets. Default: 0 (no change).
          deltapsym - Increase of point symbols for distinct data
                      sets. May be positive or negative
                      integer number. Default: 0 (no change).
                      If psym exceeds -7..7 it will be set at 0 (no
                      symbol). Therefore it is recomended to
                      plot data sets with lines with a negative
                      deltapsym (to decrease and restart from 0).
           xcol     - Column to use for x values. This might be used
                      to display multi dimensional data and select
                      the abscissa dimension. Default is column 0.
           ycol     - Column to use for y values. This might be used
                      to display multi dimensional data and select
                      the ordinate dimension. Default is to use the y
                      values for displaying.

           None.
