How to Read a Line Graph
- 1Read the title, both axes (x = time, y = value), and the legend (which line is which).
- 2Identify the time period — is it years, months, decades?
- 3Identify the unit — %, millions, thousands, kilograms?
- 4Count how many lines there are — each line = one data series to describe.
- 5Ask: What is the OVERALL trend? Rising? Falling? Fluctuating? Stable?
