The semilogplot command creates a 2-D plot where the horizontal axis has a logarithmic scale.  The horizontal range must be given in a call to semilogplot.

The semilogplot command provides support for 2-D log plots of one or more functions specified as expressions, procedures, or lists of points.  See plot/function for more information on the different input forms.

The horizontal and vertical range arguments h and v define the axis labels and the range over which the function(s) are displayed. They take one of the following forms: string, low..hi, or string=low..hi, where low and hi are real constants. See plot/range for further information.

Remaining arguments are interpreted as options which are specified as equations of the form option = value. These options are the same as for those found with the plot command. See plot/option for more information.

An alternative method for creating a two-dimensional plot where the horizontal axis has a logarithmic scale is to use the plot command with the axis option.
