When values are only 1 and 0 in callback - strange middle values are being included

https://codepen.io/anon/pen/MrbRBw?editors=1010 <-- this demo illustrates my problem

So I have multiple graphs and using one graph as a parent graph for inheriting the same patterns. And one thing that differs from all the graphs are the Y axis custom values. On some I want to return custom values and on some the original ones. With the custom one everything works as expected, but with the original ones on occasion when I only have 0 and 1 values I get some bizarre middle values, which are not there and ofc I don't want to display them.

Expected Behavior

Well I should only see 0 and 1 values or at least tell me how to achieve this?

Current Behavior

The opposite

Environment

• Chart.js version: 2.7
• Browser name and version: Newest Ubuntu chrome

   if (Math.floor(data) === data) {
                        return data;
                    }

Was what I was looking for - case closed !

@neorganic looks like this is fixed by #4943 and will be shipped in the next release (duplicates #4928)
