In general
<A HREF=r37_0551.html>plot</A> tries to generate smooth pictures by evaluating
the functions at interior points until the distances are fine
enough. This can require a lot of computing time if the
single function evaluation is expensive. The refinement is
controlled by the switch <em>plotrefine</em> which is
<A HREF=r37_0210.html>on</A>
by default. When you turn it
<A HREF=r37_0209.html>off</A> the functions will
be evaluated only at the basic points (see
<A HREF=r37_0565.html>plot_xmesh</A>,
<A HREF=r37_0566.html>plot_ymesh</A>).
