Figure 8-8. Adding annotations to scatterplots
Labels, tooltips, and annotations are three different ways to call attention to specific marks,
or data points, in our views. Which we decide to use depends on whether we want to label
many points, no points, or specific points. We can also use a combined approach as we did in
the previous examples, showing some labels and allowing a user to discover other names
through interaction.
Making it Exploratory
The last element we'll add with this scatterplot are the Quick Filters you see in
Figure 8-1
on
the righthand side. Why would we bother adding these filters? If our goal is to
explain
how
remarkable Wayne Gretzky was, our job is done. However, if we'd like to give our audience
the ability to
explore
the data to find other insights about the top 100 players, we still have
some work to do.
We've mentioned it already, but it's worth repeating: adding Quick Filters is an easy and
powerful way to explore data in Tableau. In the case of the hockey player career points data
set, we'd like to add the ability to filter by position, career penalty minutes, and career +/−
