You are potentially using ECMAScript syntax in a declarative mode. To achieve reasonable performance in this pseudo-declarative mode, you would need hints as to the sampling interval to use. Tools that graph functions, like gnuplot, typically have a parametric mode, as well as the simple y = f(x) mode. > > <funcCoordSystem> > <func f="Math.sin(x)" d="(-2 * Math.PI; 2 * Math.PI)" /> > <func f="Math.cos(x)" d="(-2 * Math.PI; 2 * Math.PI)" /> > </funcCoordSystem> -- David Woolley Emails are not formal business letters, whatever businesses may want. RFC1855 says there should be an address here, but, in a world of spam, that is no longer good advice, as archive address hiding may not work.
