How can I generate a horizontal line starting at x = 0 up to a graph (see figure, red line)? The x, y coordinates are of course available for the graph.

If you have the xlimits (x0,x1) and the y-value..the required equations is y = k.
x = 1:10 ;
k = 3 ;
y = k*ones(*Size(x)) ;
Also have a look on line.

The value x1 should be freely chosen. From the point of intersection with the function (x, y) the line should run horizontally to x = 0.
