nomogram

[nom´o-gram]
a graph with several scales arranged so that a straightedge laid on the graph intersects the scales at related values of the variables; the values of any two variables can be used to find the values of the others.

nom·o·gram

(nōm'ō-gram),
1. A form of line chart showing scales for the variables involved in a particular formula such that corresponding values for each variable lie in a straight line intersecting all the scales.
2. A line chart in toxicology that relates time since toxic ingestion with blood levels of the offending agent to estimate levels of toxicity and to guide therapy.
Synonym(s): nomograph (2)
[G. nomos, law, + gramma, something written]

/nom·o·gram/ (nom´o-gram) a graph with several scales arranged so that a straightedge laid on the graph intersects the scales at related values of the variables; the values of any two variables can be used to find the values of the others.

nomogram

[nom′əgram, nō′mə-]
Etymology: Gk, nomos, law, gramma, a record
1 a graphic representation, by any of various systems, of a numeric relationship.
2 a graph on which a number of variables are plotted so that the value of a dependent variable can be read on the appropriate line when the values of the other variables are given.

nomogram

An alignment chart in which there are ≥ 3 abscissas, each measuring a specific parameter and mathematically or empirically defined as having a relationship to the other two; the abscissas are placed parallel to each other on an open 2-D field; a straight line drawn when 2 parameters are known allows determination of the value of a 3rd–unknown parameter

nom·o·gram

(nōmō-gram)
A form of line chart showing scales for the variables involved in a particular formula in such a way that corresponding values for each variable lie in a straight line intersecting all the scales.

tonography

Technique for measuring the facility of outflow of aqueous humour from the eye under the continuous pressure exerted by the weight of a tonometer over a given period of time. The instrument usually employed for tonography is an electronically recording Schiötz tonometer. In this technique, the pressure is continuously recorded over a four-minute period and the outflow is deduced by utilizing a specifically designed diagram, called a nomogram (which is a graphical representation of one, or more, mathematical relationships whereby the desired value may be found without calculation by placing a straight edge across the diagram). The results of tonography can indicate the presence of established glaucoma, although the technique is not very reliable for borderline cases.

(nōmō-gram)
Linear chart showing scales for the variables involved in a particular formula such that corresponding values for each variable lie in a straight line intersecting all the scales.
