Running Gnuplot

To start gnuplot, just type 
	gnuplot
on the commmand line. If you like, you can follow the command by the names of one or more files ("scripts") containing gnuplot commands. Also, if you want to keep your display window open after your gnuplot session is over, use the "-persist" command-line option: 
	gnuplot -persist script1 script2 ...
You can also mix scripts and keyboard input by using "-" as an input file: 
	gnuplot -persist script1 - script2 ...
which takes input from script1, then from standard input, then from script2. This may be useful if a plot has a standard set of opening and closing commands, but you want to add your own options in between.
