Figure 8-13 shows what the Sheet should look like after following these steps.
We can see right away that Gretzky has company at the top of this list. He and Mario
Lemieux both stand apart from the rest, don't they? Their overall points per game are sub-
stantially higher than the rest of the top 100. We can also see that Lemieux scored goals at a
higher rate than Gretzky, as indicated by the dark gray bars, and that Mike Bossy scored
more goals per game than either of them.
It's a little more difficult to compare their Assists per Game rates, though, wouldn't you say?
This is one drawback of the stacked bar chart: it's easy to compare the lengths of the first
bars (dark gray in this case) and the overall lengths of the stacked bars, while the bars
without a common baseline are much more difficult to compare. What if it was more import-
ant to enable a comparison of assists?
NOTE
If it's more important to be able to communicate the comparison of the two variables
themselves, and less important to compare the overall sum, then a dual dot chart is pre-
ferred to the stacked bar.
