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.
