I see the same problem.
I fixed it by adding:
if graphView.rangeMin == graphView.rangeMax {
graphView.rangeMin -= 1
graphView.rangeMax += 1
}

This happens when i try to put 0 as rangeMin and 10 as rangeMax

Ah, damn. This bug was fixed in the pre Swift 3 version. It appears it has been resurrected during the conversion to Swift 3.

Would you mind posting the code where you configure the graph view? I can't seem to reproduce it here.

I also saw this Issue happen.
It occurs in my instance when both the ScrollableGraphView rangeMin and rangeMax are 0 while the values in the data are all 0.
It appears to fail on line 867 of ScrollableGraphView.swift
The firstDataPoint.location CGPoint is (in our case) CGPoint(x=50, y= Nan)

Some code to recreate it:
var test: [Double] = [0,0,0,0,0,0,0]
graphView.rangeMax = 0
graphView.set(data: test, withLabels:[**"MON",**"TUES",**"WED",**"THUR",**"FRI",**"SAT",**"SUN"])
I worked around it by making sure that both the min and max ranges can't be 0 at the same time.
Hope this helps :)

I ran into this issue as well and the above fix did not fix my issue. My issue was caused by having the ScrollableGraphView's .frame be equal to .zero (I'm working with autolayout constraints, so the frame was not yet set at the time of graphing).
I fixed my issue by calling self.layoutIfNeeded() to adjust the graphView's frame.
