Figure 6-16. Bar Chart (Histogram).

Each bar is 1/3 inch wide (100/300 inch). The distance from the left side of one bar to the left side of the next bar is one inch (300/300). This allows other bars to be added through a separate command.

Bar 1 will be 1 2/3 inches (500 x 1/300 inch) high, bar 2 will be two inches high (600 x 1/300 inch), and bar 3 will be 2 2/3 inches high (800 x 1/300 inch).

NOTE

The y-increment determines the scaling. Only integers (1, 2, 3, 4, etc.) are valid. If you are charting sales figures in thousands of dollars, the y- increment should be small (for example, 1). If you are charting the number of customer complaints per period, the y-increment should be high (for example, 100 or more). Be aware that the bar height must not exceed the total printable area of the page.
