Adjusting # of Decimal Places Chart.js rounds to?

Hello I am rather new to ChartJS so I do apologize that this is probably a simple question.
I currently have a working chart re-created here from the codepen template: http://codepen.io/benjamincrypto/pen/NRKkVb?#anon-login
I have noticed that the rounding is dynamic (using nice numbers?)

My question is: How would I get the Y-Axis to round to the 8th (or more) decimal place?

I have tried applying variations of scaleLabel: “<%%=value/100000000%%>”, in various places after researching on SE, but can’t seem to quite make it work – any ideas?
Thanks!
