Gnuplot

GNUPLOT is a command-driven interactive function plotting program. It is case sensitive (commands and function names written in lowercase are not the same as those written in CAPS). All command names may be abbreviated, as long as the abbreviation is not ambiguous. Any number of commands may appear on a line, separated by semicolons (;). Any command-line arguments are assumed to be names of files containing gnuplot commands. Each file is loaded with the load command, in the order specified. Gnuplot exits after the last file is processed. Commands may extend over several input lines, by ending each line but the last with a backslash ( \). The backslash must be the LAST character on each line. The effect is as if the backslash and newline were not there. That is, no white space is implied, nor is a comment terminated. Therefore, commenting out a continued line comments out the entire command (see comment). In this documentation, curly braces ({}) denote optional arguments to many commands.
