In science and engineering, a semi-log graph or semi-log plot is a way of visualizing data that is changing with an exponential relationship. One axis is plotted on a logarithmic scale. All functions of the form y = λa ^{− γx} form straight lines, since taking logs of both sides is equal to Part of a scientific laboratory at the University of Cologne. ... Engineering is the application of scientific and mathematical principles to develop economical solutions to technical problems, creating products, facilities, and structures that are useful to people. ... In probability theory and statistics, the exponential distributions are a class of continuous probability distribution. ... A logarithmic scale is a scale of measurement that uses the logarithm of a physical quantity instead of the quantity itself. ...

log(y) = − γxlog(a) + log(λ)
