Why should a bar chart's value axis start at zero?

  1. A Truncating the axis exaggerates differences and misleads the reader
  2. B Excel requires it
  3. C Otherwise the chart will not render
  4. D It improves performance
Answer

Truncating the axis exaggerates differences and misleads the reader

Bar length encodes magnitude, so a truncated baseline distorts it. Line charts showing change over time may reasonably not start at zero.
