Abstract

The value of plotting business performance data over time on a semi-logarithmic graph has been advocated, but in a somewhat off-hand and intuitive way. While examples have been discussed, no mathematical justification has been given. In this paper, we give such a justification in order to underscore, and perhaps acquaint the reader with this simple yet powerful graphics tool. We also discuss and illustrate an extension of the idea underlying this technique. These methods are particularly useful with spreadsheet packages which inculude graphics capabilities.
