My good friend Ray Dillman, a graphic artist who makes commercials and such has long lamented the poor training scientists receive in data presentation. He had some time on his hands and made my screen shot of the GPR look so much better. Thanks Ray and I hope the fonts in the jpg came out correctly.
If you are interested in learning more Wikipedia has a nice entry on GPR (and the pictures there are not much better than in my previous post).
Ironically we just finished a mini-course at the Fiske Center that was called “Charts, graphs, & tables” that I gave. Needless to say, the focus was on content. Maybe I should expand the course to include at least a mention of aesthetics.
