Adds vertical lines to 3D figure at specified locations.
- h = zline(x,y,lc)
ZLINE draws a vertical line on an existing 3D figure from the bottom axis to the top axis at at postions defined by x and y which can be a scalar or vector.
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, ZLINE draws a vertical green line at 0,0
Output h is the handle(s) of line(s) drawn.
plots a vertical red line at x = 2.5 and y = 1.2.
