Canvas: JavaScript Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1

Question

And it works in firefox but not in google chrome. Internet explorer also has problems but thats pretty much a given when using HTML5 Canvas.

Anyways I'm trying to figure out why it throws the error: Uncaught Error: INDEX_SIZE_ERR: DOM Exception 1

When the arrays clearly have all those elements, I even logged their size and it says 100.

Any help/guidance would be greatly appreciated.

It happens because circlesR values can become negative at some point. The radius of a circle cannot be negative. — zneak, Mar 14 '10 at 22:39

Zneak has the answer right, I just fixed it.

I wasn't doing the radial boundary testing early enough... Canvas doesn't like it if you have a negative radius :-).

Thanks zneak!
