4.1.4.1 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 <v>`) and a resource, `gnuplot*pointsize: <v>`, 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.
