Thanks for the advice, Jeff.  That's really what I was looking for.

I still have another question (I'm sorry for that).  Is it possible  
to increase the linewidth of the box plot (and change the color -  
i.e., from blue to black)?    In the documentation, I don't see any  
option for boxplot regarding that point (the "widths" option refers  
to the width of the box, not the line).

I agree it is a cosmetic question but I think it would be better in a  
paper if I can change the linewidth and color.

Thanks in advance.

Keep on rockin'
