In this chapter, we describe advanced use of PLplot.
PLplot supports a large number of command line arguments, but it is
up to the user to pass these to PLplot for processing at the
beginning of execution.
plparseopts is responsible for parsing
the argument list, removing all that are recognized by PLplot, and
taking the appropriate action before returning. There are an
extensive number of options available to affect this process. The
command line arguments recognized by PLplot are given by the -h
% x01c -h Usage: ./x01c [options] PLplot options: -h Print out this message -v Print out the PLplot library version number -verbose Be more verbose than usual -debug Print debugging info (implies -verbose) -dev name Output device name -o name Output filename -display name X server to contact -px number Plots per page in x -py number Plots per page in y -geometry geom Window size, in pixels (e.g. -geometry 400x300) -wplt xl,yl,xr,yr Relative coordinates [0-1] of window into plot -mar margin Margin space in relative coordinates (0 to 0.5, def 0) -a aspect Page aspect ratio (def: same as output device) -jx justx Page justification in x (-0.5 to 0.5, def 0) -jy justy Page justification in y (-0.5 to 0.5, def 0) -ori orient Plot orientation (0,2=landscape, 1,3=portrait) -freeaspect Do not preserve aspect ratio on orientation swaps -portrait Sets portrait mode (both orientation and aspect ratio) -width width Sets pen width (1 <= width <= 10) -bg color Background color (0=black, FFFFFF=white) -ncol0 n Number of colors to allocate in cmap 0 (upper bound) -ncol1 n Number of colors to allocate in cmap 1 (upper bound) -fam Create a family of output files -fsiz size[kKmMgG] Output family file size in MB (e.g. -fsiz 0.5G, def MB) -fbeg number First family member number on output -finc number Increment between family members -fflen length Family member number minimum field width -nopixmap Don't use pixmaps in X-based drivers -db Double buffer X window output -np No pause between pages -server_name name Main window name of PLplot server (tk driver) -dpi dpi Resolution, in dots per inch (e.g. -dpi 360x360) -compression num Sets compression level in supporting devices -drvopt option[=value][,option[=value]]* Driver specific options
Some options are may not be recognized by individual drivers. If an option is not recognized but should be, please contact the driver author via the plplot mailing lists.
