Misleading graphs

Truncated axes, 3D pies, cherry-picked ranges — how charts lie.

Graphs lie when axis ranges are cropped, scales distorted, or 3D effects added.

Watch for

  • Y-axis not starting at 0.
  • Inconsistent bin widths.
  • Logarithmic scales presented as linear.
  • 3D pies (slices look bigger by perspective).
