Even the data stands on the baselines.
“All illustrations, photographs and statistics have the size of 1, 2, 3 or 4 grid fields.” — Müller-Brockmann, p.14. Statistics. A chart in this library takes grid fields like a photograph, and then obeys one law more: a bar may only be a whole number of text lines tall, because no distance on the page may be a half line (pp.58–59), and the data is not excused.
That forces a visible, honest rounding. Drag the chart's depth and watch the bars re-quantise: fewer lines, coarser truth; more lines, finer. The chart declares its resolution the way a ruler declares its smallest mark — and the readout below shows exactly what each value became.
