Line graphs — showing change over time

A line graph plots points and connects them with line segments. Great for data that CHANGES OVER TIME.

Common uses: daily temperature, monthly rainfall, weekly sales, attendance per day.

Reading a line graph:

  1. Find a point on the horizontal axis (time).
  2. Go up to the line and then across to the vertical axis (value).
  3. Note trends: rising, falling, or flat.
Example
If the line rises steeply from Monday to Friday, the value grew fast that week. A flat line means no change. A downward line means decrease.
💡 Tip:Bar graph compares separate categories. Line graph shows change in ONE thing over time.
