8.27.24 logscale

set logscale [<axis> ... ] [<base>]

The logscale setting causes an axis to be laid out with logarithmically, rather than linearly, spaced intervals. For example, issuing the command:

set log

would cause all of the axes of a plot to be scaled logarithmically. Alternatively only one, or a selection of axes, can be set to scale logarithmically as follows:

set log x1 y2

This would cause the first $x$- and second $y$-axes to be scaled logarithmically. Linear scaling can be restored to all axes via:

set nolog

or:

unset log

and to only one, or a selection of axes, via:

set nolog x1 y2

or:

unset log x1y2

Optionally, a base may be specified at the end of the set logscale command, to produce axes labelled in logarithms of arbitrary bases. The default base is 10.
