The multiple command builds a composite plot.

The parameter plotcommand is a Maple plotting command, applied to the plot arguments plotargsi.

Each parameter plotargsi is a list of arguments for plotcommand, the plotting command.  To plot the sine function for two different frequencies, you can use:

plots[multiple]( plot, [sin(2*x), x=-Pi..Pi], [sin(3*x), x=-Pi..Pi] );

The remaining arguments to the multiple command are interpreted as options.  They are equations of the form option = value, and are passed on to the plots[display] command.
