Logarithmic scale

A logarithmic scale is a way of displaying numerical data over a wide range of values in a way that can make it easier to visualize and interpret. Instead of each unit being the same size as on a linear scale, where equal intervals on the axis represent equal differences in value, a logarithmic scale represents equal intervals as equal ratios. In a logarithmic scale, each tick mark on the axis represents a power of a base number, commonly 10.
