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.
Graphs and charts turn lists of data into pictures that are easier to understand.
Then check what each bar, point or slice stands for. Good graphs help us answer questions such as which item is most popular or how the weather changed during a week.

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 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.
