plot

Plots a given dataset in 2D axes.

Syntax

h = plot(y)

h = plot(x, y)

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

h = plot(x, y, fmt)

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

h = plot(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 for 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.

Examples

Simple plot example:
clf;
plot(rand(1, 10));
Simple plot example with format:
clf;
plot(rand(1, 10), 'r:+', 'linewidth', 1);
Simple plot example with format and multiple lines:
clf;
x = [0:0.1:2*pi];
plot(x, sin(x), 'g', x, cos(x), 'm');

Comments

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