I would like the ability to add a legend to a column or bar chart that's created from a single series which has been colored with unique colors per category. In my example, I have a Nominal variable that I'm charting in a bar chart, using multiple colors in a single series. If I select to show the legend (it's off by default), the legend only shows a single color (for the single series), and not the labels for the different colors. See screenshot for an example of what it looks like right now.

Instead of this, the legend should show the different colors along with the different labels.
