A **Vertical Line Chart** is used to show ungrouped discrete data.

The data is similar to a bar chart, but the vertical line has no width.

The chart shows that the data is discrete (the lines do not touch each other) and that they are ungrouped (there is no width to the vertical line).

A vertical line graph shows the results of a test for Year 10.

What was the modal score?
