Curve in Neon Lights on a Glass Grid Placed in Front of Three Related Curves Painted on a Wall Surface.

1. Tubular form of the neon light lends itself particularly well to the making of illuminated

curve charts without limit in size. Colors are available to give contrast in superimposed curves. Consideration should be given to glare as lights may be too brilliant for easy reading.

2. On the glass-ruled grid for the neon lights above it is unfortunate that the zero line of

the death rate was omitted.

3. For other methods of display, see "Displays and Exhibits," pages 486-493.

Chapter 36 COMPONENT PARTS SHOWN BY CURVES

IN THE chapters on "100% Bar Charts." pages 92-105, and "Component Bar Charts," pages 132-141, the method of showing component parts in bar chart form is illustrated. The charts in this chapter present the same type of information in the form of curves.

Other terms used for charts in which component parts are shown by curves are percentage charts, band charts, 100% band charts, percentage band charts, and surface charts. The terms "100% band chart," "percentage chart," and "percentage band chart," designate only those charts in which material is presented qn the basis of 100%. See 297B, 299B. and 300. The terms "surface chart" and "band chart" may be used when referring to either of the two charts shown on page 300.
