Drawing a time-series graph
Drawing a time-series graph.
- Label axes, units and scales clearly.
- Bar charts use separated bars; time-series graphs join points in time order.
- Read the key when comparing more than one group.
Example 1
Draw the time-series graph.
| Day | Temperature (°C) |
|---|---|
| 1 | 12 |
| 2 | 14 |
| 3 | 13 |
| 4 | 18 |
| 5 | 16 |
| 6 | 19 |
Change Final reading minus initial reading gives the overall change.
Example 2
Draw the time-series graph.
| Day | Temperature (°C) |
|---|---|
| 1 | 13 |
| 2 | 15 |
| 3 | 14 |
| 4 | 19 |
| 5 | 17 |
| 6 | 20 |
Change Final reading minus initial reading gives the overall change.
