| d'Ocagne nomogram | An alignment chart consisting of an arrangement of three or more graduated lines (straight or curved), each constituting a scale of values of a variable, constructed so that any straight line crossing these scales connects the simultaneously compatible values; from values for any two variables, the values of all other variables can be determined.
