Chapter 16 BILATERAL BAR CHARTS

■HE TERM bilateral may refer to a curve or line chart as well as to a bar chart. In a bilateral bar chart the bars extend both up and down or both to the left and to the right of a common line.

This results in a comparison of the distances from the line to the ends of the bars rather than from the bottom or line at the left.

Bilateral bar charts are especially adapted to the presentation of profit and loss data or of deviations from normal.

The following are synonyms for bilateral bar charts: two-way bar chart, two-directional bar chart. RAILROAOS
