Some claim that I get a bit crazy with math while teaching biology. I was teaching my students the advantages of semi-log and double log paper back before computers and when I was in the boonies where I had to order the paper a year ahead of time. (while climbing uphill, both ways) At any rate, you can imagine my delight when I found this freeware application written by Dr. Pillippe Marquis that let me design my own graph paper. I thought it was no longer available but recently I ran across it, again and figured I’d better share it. Try it out, I think it will produce most any form of graph paper you are interested in. You can download it here.
