A chart representing numerical relationships
A graph in which lines are graduated and aligned so that a straight edge crossing the lines allows the reading of unknown values on one line by means of known values on other lines.
Graphical assessment tool consisting of a three coplanar curves, each graduated for a different variable so that a straight line cutting all three curves intersects the related values of each variable.
a chart or table or graph that summarizes complex statistical data
a chart with three or more sides and/or curves such that the relationship between variables can be displayed along a straight line
(Or alignment chart; also called nomograph, nomographic chart.) The graphical representation of an equation of three variables (, , ) = 0, by means of three graphical scales (not necessarily straight), arranged in such a manner that any straight line, called an index line, cuts the scales in values of , , and satisfying the equation. By introducing auxiliary variables and constructing auxiliary scales, equations containing more than three variables may also be represented by nomograms.
A graph that enables one by the aid of a straight-edge to read off the value of a dependent variable when the value of two or more independent variables are given.
A computational aid consisting of two or more scales drawn and arranged so that the results of calculations may be found by the linear connection of points on them. Historically, it was used for calculating economic lot sizes or sample sizes for work measurement observations. Also called an alignment chart.
