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.
