> less triggering to an "all y-axes must have zero" guy
Ever read 'How to Lie with Statistics'? This is an example of exaggerating a smaller difference to make it look more significant. Dismissing it as just being 'triggered' is a bad idea.
In this case I would called it triggered (for lack of a better word), since, as I described earlier, a chart plotting "difference from 100%" would look exactly the same, and satisfy the zero-bound requirement, while not being any more or less dishonest
The point is less to use bad/wrong math; it's to present technically correct charts that nonetheless imply wrong conclusions. In this case, by chopping off the bottom of the chart, the visual impression of the ratio between the bars changes. That's the lie.
