Experimentation with graphical methods for data presentation is important for improving graphical communication in science. Several methods-full scale breaks, dot charts, and multibased logging-are discussed. Full scale breaks are suggested as replacements for partial scale breaks, since partial breaks can fail to provide a forceful visual indication of a change in the scale. Dot charts show data that have labels and are replacements for bar charts; the new charts can be used in a wider variety of circumstances and allow more effective visual decoding of the quantitative information. Logarithms are powerful tools for data presentation; base 2 or base e is often more effective than the commonly used base 10.
