All,
This example from the Metapost manual is beyond my expertise. The
second figure is sweet, just what I would want. Can anyone wax
philosophic for a bit and explain why the y-scaling keeps the second
function single valued?
starttext
\startbuffer[figure]
numeric scf, t[];
3.2scf=2.4in;
path fun;
fun:=(0,-1)..(1,.5){right}..(1.9,.2){right}..{curl .1}(3.2,2);
fun:=fun scaled scf;
draw fun;
\stopbuffer
\placefigure
[][fig:one]

{\processMPbuffer[figure]}
\startbuffer[figure]
numeric scf, yscl, t[];
3.2scf=2.4in;
path fun;
yscl=.1; %keep the function single valued
fun:=(0,-1yscl)..(1,.5yscl){right}..(1.9,.2yscl){right}..{curl .1}
(3.2,2yscl);
fun:=fun yscaled (1/yscl);
fun:=fun scaled scf;
draw fun;
