## logarithmic scale

a scale in which the values of a variable are expressed as logarithms. Such transformations of data are often employed to simplify the drawing of lines on a graph, where the variable values are spread over a wide range. See Fig. 213 . A good example of the use of log scales is seen in Fig. 182 where the LOG PHASE of a microbial GROWTH CURVE is illustrated. Compare LINEAR SCALE.

Suppose that f (z) is a transcendental entire function with finite order [sigma](f), and a set E [subset] (1, [infinity]) has a finite logarithmic measure and G = {[[phi].sub.1], ..., [[phi].sub.n]} [subset] [0, 2[pi]).
By Lemma 2.4 and its Remark 2.1, for any given 0 < [epsilon] < 1/2, there exists a set [E.sub.1] [member of] (1, [infinity]) of finite logarithmic measure, such that for all z satisfying [absolute value of z] = r [not member of] [0, 1] [union] [E.sub.1] and r sufficiently large, we have
