CHAPTER 7: Advanced Features
Run Chart—¬GR<line width>;<x start>;<y start>;<x-increment>;
<y-increment>;<# of entries>;<value 1>;<value 2>; ...
Draws a run (line) chart. The x,y start specifies the origin of the chart’s x,y scale (x,y axes are not drawn). The x-increment specifies the horizontal movement before the next value is printed. The y-increment determines the height of the line (multiplied by the value).
For example: ¬GR3;900;2400;150;1;5;100;300;200;500;400 draws the run (line) chart shown in Figure 7-16 below.
| Value 1 = 100 | | | |
| Value 2 = 300 | | | |
| Value 3 = 200 | | 4 | |
| Value 4 = 500 | | |
| | | |
| Value 5 = 400 | | | |
| | | 2 | 5 |
| | | |
| | 1 | 3 | |
| 1/3 inch = 100 | | |
| | | |
| (value) x 1 | | Line width = 5mm | |
x,y start | (y increment) | | |
⎟ 300/inch | | xy start (900,2400) | |
(900,2400) | | | |
| | x increment = horizontal |
| | |
| | | distance between values |

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 large (for example, 100 or more).
