While it appears that canoe and boat rentals do not move smoothly together, we do not have the monthly data to make better use of the information in the graph. To see what each point in the graph in Figure 76 represents, we can add labels to the individual points, that is, we will add the names of the months to the individual data points To do this:
Double-click on the graph or Right Click > Edit.
Select Insert > Data Labels.
Check the Label Text box.
This gives the graph in Figure 77.
