Contour - makes a contour plot
Contour [par=] [< In.H] | Tube
Make a contour plot of a seplib file
Input a real-valued (esize=4) dataset and output vplot commands for a two-dimensional contour plot of the data. (The vplot output can be viewed on a screen using the program Tube, or plotted on a postscript printer using Pspen.) Contour has many, many options to specify at what values to draw contours, where to position the plot on the page, how big to make the plot, which way to draw the axes, where to place tick marks and labels, etc. All of these parameters attempt to default reasonably. Contour also allows auxiliary input files which can be used to annotate the contour plot with symbols, curves or arrows. You may find the utility programs Window and Reverse useful pre-processing data to be plotted with Contour. See also Vppen and Box for a crude way of adding annotation, and pls and pldb for a crude way of editing.
standard seplib n1 parameter
value to contour; if not specified calculated from nc c0 and dc
[5] number of countours
[calculated] first value to contour
[calculated from c0 and nc] contour interval
determined from file size and n1 and n3
[1]
[1.]standard sampling sampleing parameter
[0.]standard seplib axis origin parameter
(0,1 n,y) (If user specifies mins or maxes then padding is turned off unless pad is specified. pad is useful if you want the length of the plot to be the same as the length of the graph.

[.75] crowd1=crowd crowd2=crowd (.75< crowd < 1.) crowds labels off the screen by expanding data on 1 or 2 axis.

[6,5,4,3,2,1,...] color for each line plotted
[7,7,7,7,...] color of each axis
[0,0,0,...] each line fat
[0,0,0,...] each axis fat
[0] (0,1 n,y) for complex data, plots arrows rather than lines
[0] 0 default is continuous. 1 fine dash 2 fine dot 3 dash 4 large dash 5 dot dash 6 large dash smalldash 7 double dot 8 double dash 9 loose dash The part after the decimal point determines the pattern repetition interval
header file for curves to be overlayed over the contours. n1=Npoints n2=Ncurves n3=Nframes esize=2*sizeof(float). The format of the data file should be: x1,y1,x2,y2,...
[6,5,4,3,2,1,...] color for each contour
