plotting, files, output
This topic summarizes those plotting options allowing you to save a plot
in a file. See also topics 'graphs', 'graph_keys', 'files'.
When keyword phrase file:FileName is an argument to a plotting command,
no plot is displayed. Instead, PostScript commands for the new plot are
written to file FileName, which must be a CHARACTER scalar or string.
If keyword phrase landscape:T is also present, the plot will be rotated
to fill an 8.5" by 11" page. If option 'dumbplot' has been set to True
(see subtopic 'options:"dumbplot"'), you will need to put dumb:F to get
a PostScript file.
With file:fileName, if keyword phrase dumb:T or ps:F is also an
argument, a low resolution "dumb" plot is written rather than
PostScript. This consists only of characters that can be printed on any
printer. On some systems, if ps:F appears and dumb:T does not, the plot
is written in a binary form appropriate to the platform (Tektronix
commands on Unix/Linux; PICT format on a Macintosh).
If the keyword phrase 'new:T' is an argument, the information in the
file is destroyed before the plotting commands are written. Otherwise,
information is added at the end of the file. It formerly was the case
tha a PostScript "prolog" was written only with new:T but now a prolog
is always written before PostScript commands.
On a Macintosh you can write the plot as an encapsulated PostScript file
by using 'epsf:T, file:fileName'. The file can be imported into some
word-processors and graphics editing programs. epsf:T is illegal with
new:F or ps:F.
On a Macintosh and in the DOS extended memory version you can write a
binary version of the plot to a file using keyword phrase
screendump:fileName. The format used is one appropriate to the
computer. The Macintosh version writes a so called PICT file and the
extended memory DOS version writes a PCX file. 'screendump:fileName' is
not legal together with dumb:T or file:FileName.
On a Macintosh, item Save Graph As on the File menu writes the graph
window currently being displayed as a PICT file.
See topics 'data_files', 'matread_file', 'vecread_file' and
'macro_files' for information on files containing sets and macros.
