I would probably just do something like...
private function renderAxis(which:String, doRemove:Boolean = true):void
if(doRemove){removePrevious();}
switch (which) {
case ("X") :
xAxis = new Sprite();
addChild(xAxis);
break;
case ("Y") :
yAxis = new Sprite();
addChild(yAxis);
break;
case ("both") :
renderAxis("X",false);
renderAxis("Y",false);
break;
}
}
