Many thanks to you and Peter Dalgaard for your advice. Instead of notches on a classic box plot, I have elected to draw a more "minimalized" box plot along the lines suggested by Tufte, and overlap a custom significance region on this.
As a statistical question, if I log-transform my data, can I no longer rely on this significance region estimation?
