Box-whisker charts come in many varieties, with the whiskers representing different statistical values: 9th and 91st percentile, 2nd and 98th percentile, 1 standard deviation above/below the mean, etc. 

Unfortunately, I can't find in the documentation any definition of what statistical value the whiskers represent in Nevron Chart box-whisker plots.  Could someone please provide me with such a definition?

Many thanks,
