The Seismic Unix package has a small collection of graphics utilities for plotting data, both in general C-style float format, and in SU format, both in the X-windows environment, for screen viewing and in the PostScript form for hard copy.
The types of plotting that are available in SU are
These programs have lengthy selfdocs, reflecting the large number of options for selecting the appearance and labeling of the plots. However, functionality such as windowing data, should be done via the programs subset or suwind as a preprocessing step before the data are actually sent to the plotting program. These plotting programs are purposely not designed to window data, as raw seismic datasets are often huge.
Also, following the ``small is beautiful'' philosophy of Unix, we have seprate, but more or less equivalent codes for generating PostScript output for hardcopy plotting.
