The Line Graph

Key Features of a Line Graph

A Line Graph should have the same key points to it as a Bar Graph:

• A Title• Both axis ruled• Clearly labelled unit of measurement on

both axis• Equal spacing on both axis• Numbers increasing at regular intervals

A Line Graph should have the same key points to it as a Bar Graph:

• The only main difference is that the horizontal labels should be on the point instead of in between the points

Identify what is wrong with this Line Graph

Create your own Line Graph• Use these figures to create your

own line graph.• Remember the Key Features of a

Line Graph.• Hint: Decide on vertical axis

spacing now.• Be careful when plotting the

years as not all the figures are in 10 year intervals.

• Complete graph and then put your hand up so I can check your graph.
