Plot two-dimensional functions and data points in many different styles, including points, lines, and error bars.
Plot three-dimensional data points and surfaces in many different styles, including contour plot and mesh.

Gnuplot features include:

Support for complex arithmetic and user-defined functions
Support for a large number of operating systems, graphics file formats, and devices
Labels for title, axes, and data points
Command-line editing and history on most platforms

To start Gnuplot, at the Unix prompt, enter:

gnuplot

At the Gnuplot prompt (gnuplot>) enter the following commands to display a graph of the sin function in a standard terminal window:
