Sorry for the lateness of my response. I am still interested in learning how to do this. Here is my code:

//Script “Lorenz Graph”
//Insert requests for global variables:
function onConfigure() {
title(“Lorenz attractor”);
ask(“General”, “initial x”, “xo”, 0);
ask(“General”, “initial y”, “yo”, 0);
ask(“General”, “Initial z”, “zo”, 0);
ask(“Parameters”, “sigma”, “s”, 10);
ask(“Parameters”, “beta”, “b”, 2.66666);
ask(“Parameters”, “row”, “p”, 28);
ask(“Euler”, “Delta t”, “dt”,.01);
ask(“Euler”, “Number of Steps”, “r”, 10);

var x = xo;
var y = yo;
var z = zo;
var i;
}

//Insert code to create score:
function onCreate() {
run(“clear”);
run(“zoom 100”);
run(“center 0 0”);
run(“rotate 0 0 0”);
run(“registerTexture background 0 0 0 0 ./Tools/background.jpg”);

//Add curve
run(“add curve 1001”);
run(“setPos current ” + xo + ” ” + yo + ” ” + zo);
run(“setPointAt current 0 ” + xo + ” ” + yo + ” ” + zo);
for(var index = 0; index <= r; index++)
{
i = index;
//evaluate Euler method
x = xo + ( s * ( y – x )) * dt;
y = yo + ( x* ( p – z ) – y ) * dt;
z = zo + ( x * y – b * z ) * dt;
//create line at xo, yo, zo to x, y, z
DrawEul(x, y, z);
//set new initial values
xo = x;
yo = y;
zo = z;
}
run(“add cursor 1”);
run(“setCurve current lastCurve”);
run(“setSpeed current auto 100”);

}
//Custom function
function DrawEul(ex, wy, ze) {
//run(“setPointAt current pNum ” + exo + ” ” + wyo + ” ” + zeo);
run(“setPointAt current pNum ” + ex + ” ” + wy + ” ” + ze);
}
