The programs that are used for PostScript plotting of general floating point data (data without SU headers) are

- PSCONTOUR - PostScript CONTOURing of a two-dimensional function f(x1,x2),
- PSIMAGE - PostScript IMAGE plot of a uniformly-sampled function f(x1,x2),
- PSCUBE - PostScript image plot of a data CUBE,
- PSGRAPH - PostScript GRAPHer Graphs n[i] pairs of (x,y) coordinates,
- PSMOVIE - PostScript MOVIE plot of a uniformly-sampled function f(x1,x2,x3),
- PSWIGB - PostScript WIGgle-trace plot of f(x1,x2) via Bitmap,
- PSWIGP - PSWIGP - PostScript WIGgle-trace plot of f(x1,x2) via Polygons.

Again, you may create binary data to test these programs by stripping off the headers of some suplane data.

% suplane | sustrip > data.bin n1=64 n2=32 d1=0.004000 nt=64 ntr=32 dt=0.004000 ns=64The dimensions of the data are n1=64 samples per trace by n2=32 traces.

% pscontour < data.bin n1=64 n2=32 title="contour" > data1.eps % psimage < data.bin n1=64 n2=32 title="image" > data2.eps % pscube < data.bin n1=64 n2=32 title="cube plot" > data4.eps % pswigb < data.bin n1=64 n2=32 title="bitmap wiggle trace" > data3.eps % pswigp < data.bin n1=64 n2=32 title="wiggle trace" > data4.eps % psmovie < data.bin n1=64 n2=32 title="movie" > data5.epsThe output files contain Adobe Level 2 Encapsulated PostScript. You should be able to view these files with any standard X-windows PostScript previewer (such as ``ghostview'').

Please note, that the output from ``psmovie'' may not work on your system. This output works under NeXTStep, but is multi-page Encapsulated PostScript, which is not generally supported by PostScript devices.

To test psgraph, make an ascii file containing a double column listing of pairs of data to be plotted such as the following

1 1 2 1.5 3 3 4 8 10 7Call this file ``data.ascii'' Then use ``a2b'' to convert the file to binary and then plot it with psgraph

% a2b < data.ascii n1=2 > data.bin n=5 % psgraph < data.bin n=5 > data6.epsNote that the ``n=5'' that is echoed by

% a2b < data.ascii outpar=junk.par n1=2 > data.bin % psgraph < data.bin par=junk.par > data6.epsto yield the same output.
