Is that their usual format fo the graph? Designed to exaggerate fluctuations by having the top and bottom of the vertical scale at the high and low points of the data. Poorly done but probably good for their business.
I don't think they're committing any subterfuge -- they are a gas price reporting service, driven by data that volunteers report via a mobile app.

If you're looking for trends, it doesn't make sense to start the graph at zero.

Further, any sensible numerical analysis would require a logarithmic price axis, not linear. But average human beings wouldn't understand that.

That’s fairly typical in charts these days. Stock prices for instance will usually be displayed this way. It’s justifiable because it gives you the best possible resolution on the y axis.

That's a very common data presentation format -- it let's you see the details much better than if your bottom is at zero. There's no "right" or "best" way to present data -- it all depends on the point you are trying to focus on. Plus, keep in mind that a lot of websites use online charting tools that make these decisions automatically and the site owners often don't put in any effort to even consider what they want to focus on, they just want a site that's low maintenance.

Gas is $1.99 where I live. Haven’t seen that for while.
We dropped back below $2/gal about a week ago and more and more stations are slipping under the threshold.

As I've remarked on many occasions in years past, the lowest gas prices at the pump almost always occur right at the New Year time frame -- a week or two before to a week or two after. Not always, but far more often than not.
