I have a collection of data obtained from calculations and I want to display it on a chart or whiz-wheel or similar, to be used "in the field" as a low-tech solution, since no computer will be available. I have a single output variable calculated from three inputs. What I want to avoid is making a giant book of tables or charts, and instead use something like the whiz-wheel that reloaders use for calculating propellant weight. Are there any nifty graphical devices out there that can display three degrees of freedom on one chart?

Per @Dan's suggestion, I googled "nomography" and found an article titled "The Lost Art of Nomography" by Ron Doerfler, published in the UMAP Journal 30.4 (2009). The article describes a compound-nomograph, which is pretty much what I need. Here is a screen shot of such a device, taken from the article:

enter image description here

The image shows a nomograph for three independent variables, but the principle could be extended to any number of variables I believe.
