Informational options

The following options request information.

`--help'

Print a list of command-line options, and then exit.

`--help-fonts'

Print a table of available fonts, and then exit. The table will depend on which display type or output format is specified with the `-T' option. graph -T X, graph -T ai, graph -T ps, and graph -T fig each support the 35 standard Postscript fonts. graph -T ai, graph -T pcl, and graph -T hpgl support the 45 standard PCL 5 fonts, and graph -T pcl and graph -T hpgl support a number of Hewlett--Packard vector fonts. All of the preceding, together with graph -T pnm, graph -T gif, and graph -T tek, support a set of 22 Hershey vector fonts. Raw graph in principle supports any of these fonts, since its output must be translated to other formats with plot. The plotfont utility will produce a character map of any available font. See section The plotfont Utility.

`--list-fonts'

Like `--help-fonts', but lists the fonts in a single column to facilitate piping to other programs. If no display type or output format is specified with the `-T' option, the full set of supported fonts is listed.

`--version'

Print the version number of graph and the plotting utilities package, and exit.
