Tim's approach requires that you have a hyphen in your label as it
replaces that hyphen with a hyphen plus a newline.
Another approach would be to split the string on spaces, and then insert
a newline at the nth space. The following example puts in a newline at
the fourth occurrence of a space:
public function defineLabel(cat:Object, pcat:Object, ax:CategoryAxis,
catItem:Object):String {
var a:Array = cat.split(' ');
var s:String = "";
for (var i:int=0; i<a.length; i++) {
s += a[i] + ' '; // reconstruct the label
if (i==3) { // insert a newline at the fourth space
s += "\n";
}
}
return s;
}
