Adding Data Labels to a Chart
The reader of your chart might be able to discern whether one of two adjacent columns is
taller than the other. However, it is difficult to compare a column in the center of a chart
with numbers along the left axis. That’s where data labels can be an advantage. This feature
works best if you have only a few data points on the chart.
Traditionally, data labels for a single-series column chart would appear above each column.
In Excel 2007, this choice is known as Outside End. The other built-in choices on the Data
Labels tab are Center, Inside End, Inside Base, and None (see Figure 2.11).
