Every number plotted in these three panels is correct, and every chart here can still mislead. A bar encodes value by length measured from the baseline, so moving the baseline changes the size of the very thing the reader is comparing. Move the floor and watch the lie factor, the effect shown divided by the effect in the data.
Both ratios above are shown rounded. The lie factor in the headline is the exact division 88.0 over 1.0, so the rounded operands will not always reproduce it by hand.
Illustrative ten-year government bond yield, twelve monthly points built for this widget. The year moves between 3.10% and 3.60%, a spread of 0.50 percentage points, and that spread fills 71.4% of the frame height here.
The cut control stops at 87.5%. A floor of 88.0% leaves the first bar with no length at all, and a ratio with nothing in its denominator has no value.
