Label the x axis values

[liliblu]

Hello, thanks for the great package and documentation.
I want to be able to give a label on the figure for each column, not just labels for the categories. I.e. I'd like it to be clear which rows are more shared between categories and which aren't. Is that possible? I couldn't figure out how to retreive the new order once it's been plotted in most to least shared order.
Thanks!
