Command-line_options

In addition to the X Toolkit options, the following options may be specified on the command line when starting gnuplot or as resources in your ".Xdefaults" file:

`-mono` forces monochrome rendering on color displays.
`-gray` requests grayscale rendering on grayscale or color displays.
  (Grayscale displays receive monochrome rendering by default.)
`-clear` requests that the window be cleared momentarily before a
  new plot is displayed.
`-raise` raises plot window after each plot.
`-noraise` does not raise plot window after each plot.
`-persist` plots windows survive after main gnuplot program exits.
The options are shown above in their command-line syntax. When entered as resources in ".Xdefaults", they require a different syntax.

Example:

         gnuplot*gray: on

gnuplot also provides a command line option (-pointsize 4#4v5#5) and a resource, gnuplot*pointsize: 4#4v5#5, to control the size of points plotted with the points plotting style. The value v is a real number (greater than 0 and less than or equal to ten) used as a scaling factor for point sizes. For example, -pointsize 2 uses points twice the default size, and -pointsize 0.5 uses points half the normal size.
