title: Coordinates of boxes in Seaborn boxplot
body: <p><a href="http://matplotlib.org/examples/api/barchart_demo.html" rel="noreferrer">This example</a>, extended <a href="http://composition.al/blog/2015/11/29/a-better-way-to-add-labels-to-bar-charts-with-matplotlib/" rel="noreferrer">here</a>, shows how to label bar plots in Matplotlib; a similar idea can be used to label box plots.  It relies on knowing the x and y coordinates of the bars, which are returned by the barplot function.  How can I do the same thing for <a href="https://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.boxplot.html" rel="noreferrer">Seaborn box plots</a>?  Unfortunately Seaborn does not return these coordinates.</p>
