4.2 Charts

Bar charts, line graphs, and pie charts have been used for years in business applications to aid the interpretation of tabular data (Figures IIA-34, IIA-35, and IIA-36). Charts are an excellent device for visualizing attribute information contained within the maps.

Figure IIA-34: Bar chart showing yield data for a wheat field.

Figure IIA-35: Comparisons of grass-seed yield (lbs acre -1) in two newly seeded tall fescue fields grazed by wild geese.

Figure IIA-36: Comparisons of grass seed yield (lbs acre -1) in an established tall fescue field grazed by wild geese.
