I don't know of a video or any online directions. Best way to learn would be in-person from an experienced shooter.
Where are you located? Are you a member of your Provincial Rifle Association?
The idea with paper plot sheets is to:
1 - record the location of the fall of each shot (put a "1" where shot #1 lands, etc)
2 - record the sight settings used for each shot, plus the "call" for each shot, plus the value attained
3 - optionally, as each shot is fired and indicated, run a vertical "elevation plot", which records the elevation setting on the sights that *WOULD* have resulted in the bullet landing perfectly on the waterline
4 - like (3), run a "windage plot", which records the windage setting that *WOULD* have resulted in the bullet landing perfectly in the centre of the target.
Examining the elevation and windage plots as they form, can show you the "centre" value for your windage and elevation, plus any trends or patterns as they form.
There is also an alternate method, called "plot-o-matic", which uses and presents the same information in a different (more visual) manner.
I know that "shotplot.ca" (an iPhone app) records fall-of-shot, but I don't think it creates elevation/windage graphs....?
"shotplot.ca" *does* have a "plot-o-matic" mode, and he does have a video on his site (just watching it now for the first time!) that shows how to use that. (**EDIT -- I've now watched the shotplot.ca video. Its plot-o-matic mode is somewhat different that how a physical plot-o-matic device works; shotplot.ca seems more oriented to after-the-shot analysis, rather than before-each-shot-planning)
Unfortunately (at this time) there are no electronic devices allowed on the line in competitions. Maybe one day this will change and we can have e-plotters and records that can be easily stored.
Thanks for the input, it helped.
I am in Belleville, ON and just started shooting at NCRRA in Ottawa. One of the guys went over it with me but of course by the time I got home I forgot.
I couldn't remember if on the call line I put how much I have adjusted the sights or the actual value on the scale..
If I start at 28 Minutes of elevation and adjust up 1 min do I place a value of 1 or 29 in the call line?

Enjoy shooting with the NCRRA guys... you certainly have a first-rate home range(!!!!)
In the "E" box, you write down the amount of elevation on your sights when the shot was fired (for example, I would write 28 and three quarters as "28 superscript 3", meaning 28 whole minutes plus three quarter-minute clicks).
In the "W" box you write down the windage used for the shot ("3 superscript 1 L", or "-3 superscript 1" would mean 3.25 MOA left). Some plot sheets have a column marked "L" and a column marked "R".... in this case you'd put "3 superscript 1" in the "L" box because it was left wind you used.
A very common convention is that if you have made no change in elevation (or windage) from your previous shot, you leave that box empty.
In the "E" and "W" boxes, you record the value on your sights (you don't record the relative changes from the previous shot).
In the "call" box, you note the error (if any) that you made when the shot broke. Some plotsheets have a blank area there (so it is just an empty rectangle), some have a circle, some have a circle with a dot in it. If you broke your shot a little high right, you can put a dot a little high and right of centre. If it was quite low right, you can put a dot on the circle or at the corner of the rectangle in the low-right position.
If you break a good shot (which ought to be the plan, and ought to get more and more common!!! ;-), you can leave the "Call" box blank. Or,for a bit of positive reinforcement you can put a check mark or a central dot in the "Call" box.
