Description

• 

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  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.

Examples

Reproduce the above plots using the operator form of input.

Create parametric log plots.

Plot multiple curves.

Plot a list of points.

Display logarithmic gridlines along the vertical axis.
