1919A. C. Haskell How to make & use Graphic Charts iv. 20 The semi-logarithmic chart has a wide use for the plotting of comparative statistics of similar kind but dissimilar magnitude. 1930R. Pearl Med. Biometry & Statistics (ed. 2) vi. 183 The scale of the ordinates is divided not in arithmetic progression but in proportion to the logarithms of numbers in arithmetic progression.
