I have this nomogram. Need to find H meaning
I can measure A and B.
Example:
Distance "A" = 1,700 mm
Distance "B" = 1,475 mm
This gives adjustment dimension "H" = 1,145 mm.
So if my Distance "A" is 1,750mm, how can I get H meaning?
What do you mean by "meaning"? Are you asking for what physical quantity it represents, or what formula would give H in terms of A and B, or just the value of H for a value of A not shown?
It may help if you show what was said about this "nomogram". (I would just call it a graph; what I think of as a nomogram is typically more elaborate than this, usually involving drawing a line two cross two or more given lines.) What is its source?
Also, what is your context? Are you just in a profession where you need to use this, or in a class where you are learning about equations? Is this a real problem, or an assignment to find the equation?
Typically would be great to get a formula. I need this to adjust my truck roof air deflector, as on the instructions there is given only this graph. Adding the full instruction and source picture. Tryed to think all the way, but seems I am missing something, can not understand this. Maybe I am thinking wrong direction.

1. Measure distance "A" from the rear edge of the door to the front edge of the bodywork.
2. Measure distance "B" from the weld flange/leading edge on the rear wall to the top edge of the bodywork.
3. Read value "H" in the nomogram.
4. Undo the screws at both the front and rear of the roof air deflector attachments.
5. Adjust the roof air deflector.
