## nomograph

(mathematics)
A chart which represents an equation containing three variables by means of three scales so that a straight line cuts the three scales in values of the three variables satisfying the equation. Also known as abac; alignment chart; nomogram.

## Nomograph

(also nomogram), a particular kind of graphic functional relation. The nomograph is used primarily as a means of computation, as a device for making specific calculations in, for example, engineering.
