Gnuplot is a command-driven interactive function and data plotting program which is included in many Unix distributions like Gnu/Linux. While often used it as a graphics calculator its features go much beyond that.
To start, type "gnuplot" from a terminal and type in
gnuplot> plot sin(x) An other good start is gnuplot> help example
Example 1: An external C program randdata.c produces a data file, which is plotted by the gnuplot program example1.gp .
Example 2: The example example2.gp shows how to plot a surface bounded by other surfaces.
Example 3: The example example3.gp shows how to plot level curves and how to redirect the output as a ps file.
Example 4: The example example4.gp shows how to draw a graph as a LaTeX picture.
More examples can be found on gnuplot-faq site.
