Hi Neil,
I think it best that I wait for version 12 because I use very different sizes of the plots in three different documents: Keynote slides in PDF, a PDF book, and an EPUB. I've got functions that change all of the formatting depending on the type of document. For the time being, I simply use the plots with the unwanted boldface labels because they are going into appendices. When the version 12 comes out, I'll simply rerun the plots and inserted them.
Thanks again for your help,
Greg
