loglog

Plots a given dataset in 2D axes with logarithmic scales for x and y axes.

Syntax

h = loglog(y)

h = loglog(x, y)

h = loglog(x, y, x, y, ...)

h = loglog(x, y, fmt)

h = loglog(..., property, value, ...)

h = loglog(hAxes, ...)

Inputs

x, y
Range of the x and y axes.
Type: double | integer
Dimension: scalar | vector | matrix
fmt
Formatting string for the curve. It can be any combination of the following strings:
  1. line style: '-', '-.', ':', '--', '-:'.
  2. line color: 'r', 'g', 'b', 'c', 'y', 'm', 'w', 'b'.
  3. marker style: 's', 'o', 'd', 'x', 'v', '^', '+', '*', '.'.
Type: string
Dimension: scalar
property
Properties that control the appearance or behavior of the graphics object.
Type: string
Dimension: scalar
value
Value of properties.
Type: double | integer | string
Dimension: scalar | vector
hAxes
Axis handle.
Type: double
Dimension: scalar

Outputs

h
Handle of the line graphics object.

Example

Simple loglog example:

cla;
loglog(rand(1, 10));


Comments

If x is omitted, the index of y is used as data to associate with x axis. Loglog takes the optional arguments to control the line style. It can be either a format string or property/value pair, or both. The form is: 
h = loglog([x,] y [, fmt] [, property, value] ...
Loglog takes more arguments to create multiple lines in one axis: 
h = loglog(x, y, x, y, ...
h = loglog([x,] y [, fmt] [, property, value], [x,] y [, fmt] [, property, value] ...
If the first argument of loglog() is an axis handle, lines are created in that axis:
h = loglog(hAxes, ...
