That's a point. I justed wanted to provide an overview for myself to see the tendencies in a direct comparement and with an easy way to distinct them, but maybe the text panel can help me with that...
Well anyway, is it right that a grouped black and white plot can contain a maxinum of 8 distinguishable lines or might there be a way to increase that? I know some graphics from papers containing lines with equally distance points on the lines (one type of point per line) as a form of distinction. Can this be realised using grouped lattice plots with regression lines? 2009/6/24 Bert Gunter <gunter.ber...@gene.com>: > Don't be silly.
