For example, the power level of a nuclear reactor can be measured at any given time.However, this power level changes with time and is often monitored. One method of relatingone physical quantity to another is to tabulate measurements. Thus, the power level of a nuclearreactor at specific times can be recorded in a log book. Although this method does provideinformation on the relationship between power level and time, it is a difficult method to useeffectively. In particular, trends or changes are hard to visualize. Graphs often overcome thesedisadvantages. For this reason, graphs are widely used.A graph is a pictorial representation of the relationship between two or more physical quantities.Graphs are used frequently both to present fundamental data on the behavior of physical systemsand to monitor the operation of such systems. The basic principle of any graph is that distancesare used to represent the magnitudes of numbers. The number line is the simplest type of graph.All numbers are represented as distances along the line. Positive numbers are located to the rightof zero, and negative numbers are located to the left of zero.MA-02 Page 72 Rev. 0
