Users want to be able to show a second statistic, not necessarily part of the original input table, either above columns in a column chart, or to the right of the bars in a bar chart. This is NOT the same as showing the data labels.

Currently, users have to create a second table with the relevant data, change it to a Specialty Table visualization, and then manually try to align this with the chart/visualization.

This creates problems with layout (it's hard to get it exactly centered), and additional complications when users have the outputs connected to combo boxes or selectors, or need to make sure that the two separate items are sorted in the same way.

It should be possible, for bar and column charts, to have a secondary statistic associated with the same labels used for the categories in the visualization. These labels should have full formatting settings (font, color, size, weight/italic, alignment.

An example is a stacked column chart with percentages showing on the column proper, with the sample size shown above each column.
