### 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.
