If 'horizontal' follows the horizon, and 'vertical' ascends from the horizon, is there a word for a line from the viewer to the horizon? Otherwise, is there a broadly accepted business term for describing data where there are two horizontals, but one is an iterative representation of the first?
Specifically, this word would be used in a business sense to represent a second horizontal of accompanying data that would be something of a Y axis to an X axis. (This is not immediately for purposes of verbal presentation.) Is there a specific term that describes this relation in a business context? I want a word that won't alienate listeners unfamiliar with unrelated fields of study.
While 'longitudinal' is helpful in describing spatial relations, this does not differentiate itself from 'horizontal', which is a common term used in business to describe a broad area, as opposed to a 'vertical' describing a focused area of specialization.
Alternatively, is there a business construct that addresses horizontality, verticality, and adds the ability to describe depth that can be utilized instead that relies on these concepts?
