Many thanks to Deepayan for providing just what I wanted. I've tried lwd many times and it does not work but lex does the trick. Thanks also to Paul Murrell for his very simple suggestion of using lower case o for an open circle since bold works on letters and to Bert Gunter for suggesting an overplotting technique to try if nothing easier was suggested.
