i think that you need to change your point of view when studying influence lines.
When you plot a BMD, you plot bending moment among the x axis. function of the bending moment is only dependant on x (for a given load of course), so M = function(x)
Now, lets make it more complex. suppose that you have a point loading on a beam. but you don't know exactly where it is. To be able to formulate some sort of solution, say it is place somwhere on the beam, at an unknown position "a".
You can now write M = function (x,a)
Now you can plot several BMD, depending on the position of the loading (the "a" parameter).
Ok, now that we made it complex, lets make it easyier:
Say that you dont want to know the moments on all the beam. but only at a particular point of the beam, say at position "x_fixed".
The previous moments function becomes M = function(x_fixed,a).
The only parameter you can vary is "a". and the results that you will get are only valid for the particular x position you chose earlyier (x = x_fixed).
This is called an influence line, at a particular x ordinate...
For i don't know what reason, influence line have always been confusing... don't worry.
