How to give a long vertical line throughout one particular plot that contains multiple subplots.
I do not want annotation command.
I would like to use something like
however this command does not show-up over entire range of subplots. I attach a smiliar figure below.
I want to specify (x,y) with respect to one of the subplots and then get a veritcal line througout the subplots.

x = 1:10 ;
y = rand(1,10) ;
hold on
x1 = 5*ones(1,10) ;
y1 = linspace(min(y),max(y),10);

When you say subplot, do you mean multiple lines draw in the same axes, or possibly even multiple overlapping axes? Or do you mean by using subplot() ?
If you mean by using subplot() then you have a few choices:
  1. Use annotation(), as annotation() ignores subplot boundarys
  2. create a large axes overlapping everything, and drawing the line inside that axes; you would set the background color of the axes to 'none' so the other axes show through. You have to be careful when you use subplot() with this, as subplot() will tend to delete overlapping axes
  3. pick one of the axes and turn clipping off for it, and then draw a line. It is possible to draw outside of an axes if clipping is off

Yes, @walter,
Clipping off worked for me!
Thank you so much.
Thank you KSSV for putting efforts
