Input data set; maximum number of 10. (Only one input allowed for MSS data)
QPLOT2 provides the user with the capability of specifying the name of the output file. If a name is not specified, QPLOT2 identifies the output file as 'qplot.gpi' or qplot.eps.
KEYWORD - VALID=(GNUPLOT,EPS) EPS Specifies POSTSCRIPT plotting, else GNUPLOT is assumed. If neither 'PLOTFMT nor PLOTOUT are specified the output table will still be generated with the name qplot2.asc
Specifies one or more lines to be plotted. Following the keyword, each plot is specified by a set of five numbers. The first value in each set specifies the Input Data Set Number and the remaining four values specify the Starting Line, Starting Sample, Ending Line, and Ending Sample. (No Default). NOTE: The line plotted will cover SQRT((EL-SL)**2+(ES-SS)**2) "relative samples" along the horizontal axis and will start at "relative sample" 1.
Specifies one or more spectral plots. This keyword requires that the input be in mss format and that NCHAN is specified. Following the keyword, each spectral plot is specified by a set of two numbers. The first value in each set specifies the Line and the second value the Sample of the point within the first channel through which the spectral plot is to be done. (No Default)
Used to specify the title of plots (Max length of 52 characters). (Default is 'IPL LINE PLOT', or for spectral plots, 'IPL SPECTRAL PLOT')
Specifies that the title will be written within the 8.5 x 11 area (if the y axis length is less than or equal to 7 inches). (Default is to place the title at the top of the page)
Specifies the title for the X axis (Max length of 52 characters). (Default is 'Relative Sample Number')
Specifies the title for the Y axis (Max length of 52 characters). (Default is 'DN Value')
Specifies the Font size, in points, for Plot Text (Default is 12)
Inhibit overprinting of VICAR labels on plot Sometimes there are just way too many labels (default is LABELS)
Specifies that labels will be written within the 8.5 x 11 space. (Default is to place the labels at the top of the page.)
Causes DN values to be scaled linearly so that the largest value becomes 1. The length of the y axis is set to 5 inches. (Default is that this is not done.)
Causes DN values to be scaled by the following equation: OUT=SQRT(IN**2-RDS**2). (Default is that this is not done)
Specifies that subsequent lines on the same plot will be displaced by the given amount. This is specified in terms of the final plotted vertical values, rather than input DN, in the cases where the input values are scaled. (Default is 0.0)
Specifies the length in inches of the X axis. (Default is 9.0; Max is 72.0)
Specifies the length in inches of the Y axis. (Default is 7.0; max is 12.0)
Specifies the scale used along the X axis. The X axis will be drawn going
from a minimum of the first value to a maximum of the second. The defaults
for these values are obtained by determining the minimum and maximum X
values to be plotted on the axis and then passing these values to the
subroutine SCALE.
SCALE determines the scaling so that 1 inch along the axis will always be
an interval of 1,2,3,4,5,6 or 8*(10**n) units. This usually results in
having the plotted lines occupy only a portion of the axis. By using the
XSCALE keyword the user can force plots to occupy a greater portion of the
X axis. Axis values are printed every inch, however, and if it is desired
that these values be nice round numbers the quantity:
(XSCALEMAX-XSCALEMIN)/XLENGTH
should be a nice round number.
Specifies the scale used along the Y axis. The Y axis will be drawn going
from a minimum of the first value to a maximum of the second. The defaults
for these values are obtained by determining the minimum and maximum Y
values to be plotted on the axis and then passing these values to the
subroutine SCALE.

Allows the user to rescale the actual x (sample) data values of the lines to be plotted. XVALUES is followed by two real values specifying the minimum and maximum x values. The first value (the minimum) is the point along the X axis where the first data point will be plotted. The second value (the maximum) is the point along the X axis where the last data point will be plotted. (DEFAULTS: XMIN=1.0, XMAX=SQRT[(EL-SL)**2+(ES-SS)**2]+1
Allows the user to rescale the actual y (DN) data values of the lines to be plotted. YVALUES is followed by groups of two real values, one group for each line to be plotted. The two values in each group specify the minimum and maximum y values. The first value (the minimum) is the point along the Y axis where a DN of zero will be plotted. The second value (the maximum) is the point along the Y axis where a DN of 255 (32767 for halfword data) will be plotted. (DEFAULT: YMIN=0.0, YMAX=255 (byte) YMAX=32767 (halfword) )
