Semi-log plot

Common card · No. 497308

In science and engineering, a semi-log plot/graph or semi-logarithmic plot/graph has one axis on a logarithmic scale, the other on a linear scale. It is useful for data with exponential relationships, where one variable covers a large range of values. All equations of the form y = λ a γ x {\displaystyle y=\lambda a^{\gamma x}} form straight lines when plotted semi-logarithmically, since taking logs of both sides gives log a ⁡ y = γ x + log a ⁡ λ . {\displaystyle \log _{a}y=\gamma x+\log _{a}\lambda .} This is a line with slope γ {\displaystyle \gamma } and...
