Purpose
Place a vertical line in an existing figure.
Synopsis
- h = vline(x,lc)
Description
VLINE draws a vertical line on an existing figure from the bottom axis to the top axis at at postions defined by x which can be a scalar or vector. If no input is used for x the default value is zero {default x = 0}.
Optional input lc is used to define the line style and color as in normal plotting (see MATLAB PLOT command). If no inputs are supplied, VLINE draws a vertical green line at 0.
Output h is the handle(s) of line(s) drawn.
Examples
vline([2.5 3],'-r')
plots a vertical red line at x = 2.5 and 3.
