Week 8: Communicating with data

Completion requirements

This vertical bar chart is the same as the previous chart except each bar has been divided into components to represent the age categories of the guests at the hotel of child, adult and senior. For the Irish bar, the first component representing the number of children stretches from 0 to 8 on the vertical scale; the second component stretches from 8 to 13 and represents the number of adults and the third component stretches from 13 to 17 and represents the number of seniors. For the British bar, the first component representing the number of children stretches from 0 to 4; the second component stretches from 4 to 10 and represents the number of adults and the third component stretches from 10 to 14 and represents the number of seniors. For the mainland European bar, the first component stretches from 0 to 3 and represents the number of adults and the second component stretches from 3 to 4 and represents the number of seniors. For the rest of the world bar, the first component representing the number of children stretches from 0 to 6; the second component stretches from 6 to 10 and represents the number of adults and the third component stretches from 10 to 12 and represents the number of seniors. On the right-hand side of the graph is a key to the chart. For each category there is a small rectangle containing a sample of the shading used and labelled with the category. An arrow points to the rectangle and states ‘key or legend’.
