Sometimes, when a plot has drastic changes in one of its variables, it
is useful to use a log scale on that axis. For instance, the graph of
cosh(x) for x=[-10,10] looked like:
If we wanted to use a logscale on the y axis, we would use the
set logscale command. The usage of this command is
To see what logscale is being used, type:
To turn logscaling off for a axis, use
We if typed the following lines in,
We would get the following graph.
- set logscale y
- plot cosh(x)
This can also be useful for data plots.
