How to Prepare Graphs

In earlier editions of this book, I gave rather precise directions for using graph paper, India ink, lettering sets, etc.
Graphs had been prepared with these materials and by these techniques for generations.

Now, however, we all live in a world revolutionized by the computer. The graphic capabilities of computers have
increased greatly in recent

years. And, now that ink jet and laser printers have largely replaced the inexpensive but poor-quality dot-matrix
printers, most scientific laboratories have the capability of producing publication-quality graphs by computer methods
(see "Creating Graphics Electronically for Scientific Papers," below).

The techniques of producing graphs electronically vary from program to program. However, the principles of
producing good graphs, whether hand-drawn in the old way or computer-drawn by the most modern programs, do not
vary. The size of the letters and symbols, for example, must be chosen so that the final printed graph in the journal is
clear and readable.

The size of the lettering must be based on the anticipated photographic reduction that will occur in the printing
