Purpose
Adds a line on the current axes with a given slope and intercept.
Synopsis
- h = abline(slope,intercept)
- h = abline(slope,intercept,...) %additional linestyle information
Description
ABLINE draws a line on on an existing axes with a given slope (slope), and intercept (intercept). If a 3D plot is shown, (slope) and (intercept) can be 2-element vectors describing the slope and intercept of the line in the y- and z- dimensions. Optional line style information can also be included. For more information on linestyle information, see help on the LINE command. The output (h) is the handle of the plotted line object.
Examples
abline( 3, -1, 'color', 'r', 'linestyle', '--')
plots a dashed red line with a slope of 3 and an intercept of -1 on the axes.
