I went to Kinko's at lunch and had the graphs enlarged to 11 x 17, they will be MUCH easier to wrok with (at least for my old eyes). Unfortunately without thinking ahead I had them laminate the charts.......... I was going to color code them and forgot all about it.
Ideally I should have taken the enlargements home, color coded and taken them back to laminate. I am going to see how difficult they are "as is", I might end up redoing them.
