Agree on use of terminology, but then 'graph' is just a process of drawing. Like 'photograph' drawing with the aid of light. On that basis, it's arguable that an instrument which draws oscillations on the screen of a tube could be called an 'oscillograph' rather than the permanent record of those oscillations (or would that have been called an 'oscillogram?'
Electric trains pick up power via a 'pantograph' although no record is being made, it's so-called because it looks like the drawing/scaling instrument called a 'pantograph'. Though even then, it's the name given to the instrument, not the drawn record!
Sorry, no help to the OP! But curious about the terminology!
