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.
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.
