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.
Figure 7-16. Run (line) chart.
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).
