Probably rounding or anti-aliasing issue, one pixel stroke is rendered incorrectly. pixelHinting doesn't really help.

Even just solid, dashed, dotted…

Thank again for your help with tips when we were developing our custom charts. Worked out well.

Any other way to reference the “pattern” variable without having to use “outerDocument”?

But can you add a bit of comments to your code? It's a bit hard to figure out all the internal chart classes and why you override some stuff, so some well placed comments would help a lot.</p> Great example.
