The set plotting command changes the default plotting program used by the plotting mode. The default is but this can be changed to any plotting program that can be driven from stdin. A maximum of 16 arguments can be passed when the program is first called. Changing the plotting program will send a KILL signal to the existing plotting program (if any). If the plotting program is set to a null string (""), will ignore all the plotting commands and warning messages will be given. Setting the plotting program to a file that cannot be found or executed will result in an error at the first pmode call.
