The logplot command creates a 2-D plot where the vertical axis has a logarithmic scale.  A typical call to the logplot command is logplot(f(x), x=a..b), where f is a real function in x and $a..b$ specifies the horizontal real range on which f is plotted.

The logplot command provides support for two-dimensional log plots of one or more functions specified as expressions, procedures, parametric curves, or lists of points.  For more information on the different input forms, see plot/function.

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.  For more information, see plot/range.

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. For more information, see plot/option.

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