Interesting, but if ever there was a y-axis that needed to 0, that is one of them. 550M revenue is a lot more than zero.

Oh wow that's an unclear graph, putting the first tick-mark at 1B gives the impression that you're starting at 0, but there is in fact over 0.5B missing from the bottom of the plot.

Good trick to remember I suppose.

Any chart that isn't zeroed out is a bad chart

There's very rare cases where it's justified; e.g. if you want to show a drop in company profits from $60.0B to $57.0B, you might want to cut the y-axis so that you're showing more detail of the loss over time (maybe so that you can correlate to the CRO's lame new "motions" that they started in January). I do think it should always be called out visually when doing that though.

It's kind of inevitable for log-plots.

Or non-absolute quantities like temperature in Fahrenheit/Celsius. (You can use Kelvin instead, but good luck interpreting that plot)

Trends in profit (and profit margin) are a better measure than revenue for most established business’s health than revenue.
