In this Photo
In the photo above the temperature range is set to 0-30 degrees C, and the color divisions within the range are readable.
explaining the nomogram
The nomogram here is simple- the temperature scale is matched to the wedge-shaped rainbow of LED colors on the left side of the page, and the colors all converge to zero on the right. By moving the temperature scale across the chart so that the max and min boundaries of the rainbow touch the temperature scale at the same points as the max and min settings of the thermal flashlight, the range and sensitivity of the flashlight's colors will be visible in the width of the rainbow color bars on the scale.
Sara liked the flexibility of knobs, and the ability to set any range. The only issue was-- how do we display color division of the range without adding an expensive/complicated graphical display to the thermal flashlight. We both liked the idea of a paper chart, and I thought up this simple nomogram. (this page on making war game nomograms is a great expanation/tutorial for complex nomograms). More Nomogram design/math
