A semilog plot, also called a single-log plot, uses a logarithmic scale on one axis and a linear scale on the other. On a plot with a logarithmic vertical axis, an exponential function 
with 
appears as the line

On a plot with a logarithmic horizontal axis, a function of the form 
appears linear. Thus semilog plots are useful for recognizing
dependence described by an exponential function
or logarithm and for comparing quantities spanning
many orders of magnitude.
The exponential decay data 
form a straight line on the semilog plot above.
In the Wolfram Language, plots with logarithmic vertical and horizontal axes are produced by LogPlot[f,
x, xmin, xmax
] and LogLinearPlot[f,
x, xmin, xmax
], respectively. The corresponding functions
for lists of data are ListLogPlot[list]
and ListLogLinearPlot[list].
