<p dir="auto">It is a common practice in scientific plottings that a barplot (or violinplot/swarmplot) has statistical annotations such as p-values marked with horizontal lines connecting the bars. There is already an implementation of this as a separate project:<br>

<p dir="auto">but having such a feature incorporated into seaborn would be very handy. Is there any interest to pursue this? -Thanks</p>
<p dir="auto">It'd be nice to be able to run some sort of statistic (e.g. Mann-Whithney) to determine group differences in bar plots when hue is provided.  When significant (p&lt;0.05) an asterisks can be added above those groups.<br>
