How to plot a graph from a table

1. Draw a **vertical axis** using the information in the **bottom row**. Look at the highest and lowest value and decide which steps to use* and if you need to use a zigzag.

*An axis should be between 5 and 15 cm long. A good way to decide what steps to use is to look at the difference between the highest and lowest value and divide this by 10. Then round off to a whole number. Good steps are 1, 2, 5, 10, and multiples of 10.
