Logscale

Syntax:

     set logscale <axes> <base>
     unset logscale <axes>
     show logscale

where 5#5axes6#6 may be any combination of x, x2, y, y2, z, and cb in any order, and where 5#5base6#6 is the base of the log scaling. If 5#5base6#6 is not given, then 10 is assumed. If 5#5axes6#6 is not given, then all axes are assumed. unset logscale turns off log scaling for the specified axes.

Examples:

To enable log scaling in both x and z axes:

     set logscale xz

To enable scaling log base 2 of the y axis:

     set logscale y 2

To enable z and color log axes for a pm3d plot:

     set logscale zcb

To disable z axis log scaling:

     unset logscale z
