3 Chart Features (X-axis and Y-axis)
3
Charts have been used for hundreds of years! Spreadsheets use many
different types of charts, but they all share some common features.
All charts have an x-axis and a y-axis. In the pictures below, we can see the
x-axis, which is horizontal and tells us when each measurement was made.
The y-axis, which is vertical, shows the value measured during each
time period.

Sometimes a graph can be confusing if it has many values. That’s why each
line uses a different colour so we can tell them apart.

It also has a ‘legend’ or ‘key’ to help us understand what each line shows.
