There’s nothing wrong with graphs whose y axies don’t start at zero. They can be used to misdirect people, but if you’re capable of actually seeing the numbers in the axes and doing a little bit of thought, they tell you exactly what one that starts at zero does.
Plus, the opaque spike is shown on the secondary y axis, which does start at 0. It’s the translucent layer that’s mapped to the primary axis.

I can’t remember the last time I saw a graph starting at a non-zero value where it showed anything other than noise whereas they almost always skew my initial impression of the data. If there’s no point in doing it but a major downside, I see no point in having them for any reason other than to mislead people.
