Read the Labels First

Start with three bar values: Alpha is 14, Beta is 17, and Gamma is 13. The printed labels say 14, 17, and 13. Use those labels before estimating from bar height. Beta is 3 higher than Alpha because the labels say 17 and 14.

A tiny chart-reading step: read printed data labels before estimating from mark height or position.
