I was still unable to reproduce the issue you described with your data. In my tests (also on Chrome on Yosemite), values are consistently placed into the same bucket across redraws.
However, I did find another issue, which is the one I think you were experiencing, where a value may be placed in the previous bucket (relative to the bucket it should have been placed in) because of floating point rounding errors in our code. I created this jsfiddle to demonstrate the issue: http://jsfiddle.net/hkg8wsmm/ As you can see, both the value 1.1 and the value 1.2 are placed in the [1.1, 1.2) bucket, when the value 1.2 should be placed in the [1.2, 1.3) bucket. Is this the issue you were describing?
