I received one more revised graph from Ramon Martinez in response to my offer in Visualizing the Table of the Graph Makeover Contest. I had said, “I’d be happy to post before and after figures if any of you want to redo your entries with the suggestions that the other reviewers and I made.” Figure 1 shows Ramon’s original figure and Figure 2 the redrawn one.
This figure is best seen in Tableau Public so that you can get information by hovering your mouse over a bar. In Figure 2, Ramon made more room for the graphs by distinguishing homeowners and renters by color, thus freeing up a column. Separating the total expenditures from the specific expenditures also made more room for the specific ones. As is often the case with graphs, just because you can doesn’t mean you should. I find the colors in the % change panel to be distracting. The length and direction of the bars provide the necessary information. I’ve seen many examples in Tableau where the ability to color by value is extremely useful but this is not one of them. The additional space for the bars in Figure 2 facilitates comparisons.
