There is no in-built method to reorder the graphics, But, as Layer.Graphics is an array, we can manipulate it with javascript array methods.
Sure, you can also use remove/add graphics, but the way I prefer is this:
Array.prototype.reorder = function (fromIndex, toIndex){
this.splice(toIndex, 0, this.splice(fromIndex, 1)[0]);
}
//an example
var a = [1,2,3,4,5];
a.reorder(3, 0);
console.log(a)
//a is now [4,1,2,3,5]This is added as an extension method, therefore it can be used with any array in your app. However, if you just want to use it in one place then simply use one line that is inside the function.
