Bar graphs

A bar graph has:

  • Categories on one axis (usually x-axis)
  • Numbers on the other axis (y-axis)
  • Equal-width bars; only the HEIGHT changes
  • A title and labels on both axes with units

Scale matters: "1 cm = 50 students" means a 4-cm bar represents 200 students.

Example
Scale: 1 unit = 10 books. A bar 5.5 units tall represents 55 books sold.

💡 Tip:Bars should NOT touch each other in a bar graph (unlike a histogram).
