All about Graphs and Charts
A graph turns numbers into a picture so that patterns are easier to see. A bar chart compares amounts in different categories, with a bar for each category. A line graph shows how something changes over time by joining points.
A pie chart shows parts of a whole as slices of a circle, with bigger slices for bigger amounts. Every graph needs a title, labelled axes and a clear scale so that the information can be read correctly.

Frequently asked questions about Graphs and Charts
When should I use a bar chart?
When you want to compare separate categories, such as the number of pets each child owns.
When is a line graph best?
When you want to show change over time, such as plant height each week.
Why does the scale on a graph matter?
If the scale is uneven or does not start at zero, the graph can exaggerate or hide differences.
