Demos and online examples

The gnuplot distribution contains a collection of examples in the demo directory. You can browse on-line versions of these examples produced by the png, svg, and canvas terminals at

http://gnuplot.info/demos

The commands that produced each demo plot are shown next to the plot, and the corresponding gnuplot script can be downloaded to serve as a model for generating similar plots.
