logarithmic

In graphic representations of physical data, a way of plotting values according to their common logarithm. The common logarithm y=log(x) of a number x is the number y for which x=10y, so the logarithm of 10 is 1, the logarithm of 100 is 2, and so on.

In ordinary ("linear") plots, the distance between the values 1 and 2 is the same as between the values 2 and 3. In a logarithmic plot, the distance between the values 1 and 10 is the same as the distance between 10 and 100 and the distance between 100 and 1000.
