Steps to Reproduce

I used the example for stacked chart and included the data I am currently working with on it.

Current Behavior

Its having a maximum of 1.2

Expected Behavior

IT should be 100% stacked, which means 1.0

Environment

- OS: windows
- Browser: chrome
- Framework: official sandbox

Any additional comments?

Update: I got it working by setting yAxis.max = 1 to force it being cut at 100%. But I still see the percentages are not being calculated correctly, maybe a JS issue ?
