How do you plot a graph in octave?

How do you plot two graphs in octave?

Octave can display more than one plot in a single figure. The simplest way to do this is to use the subplot function to divide the plot area into a series of subplot windows that are indexed by an integer. For example, subplot (2, 1, 1) fplot (@sin, [-10, 10]); subplot (2, 1, 2) fplot (@cos, [-10, 10]);
