EXAMPLE 31 Inaccuracy in relative lengths of bars in a bar graph and unclear labeling
Figure 61 is a horizontal bar graph of the three teams with the most World Series victories in baseball history. Explain what is unclear or misleading about this graph.
Figure 2.61: FIGURE 61 Inaccuracy in bar length.
Solution
Note that 127 is more than twice as many as 52, and so the Yankees' bar should be more than twice as long as the Cardinals' bar, which it is not. Finally, note the absence of a horizontal axis.
