plot data as is
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 - x. gaptol - Defines above which x difference gaps are recognized. Must be given in units of binning width=x - x. 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.
