Syntax
gline(h)
gline

you to draw a line segment in the figure with handle h

clicking the pointer at the two endpoints. A rubber-band line tracks
the pointer movement.
gline

to h = gcf
and draws in the current figure.

the handle hline
to the line.
Examples
Use gline
to connect two points in a plot:
x = 1:10; y = x + randn(1,10); scatter(x,y,25,'b','*') lsline mu = mean(y); hold on plot([1 10],[mu mu],'ro') hline = gline; % Connect circles set(hline,'Color','r')
