This section describes how multiple GL elements interact to create a bar
chart like the one shown in Figure 7-18.
Figure 7-18. Finished bar chart.
1.
Following the general steps listed in
Section 7.7.1
, we first determined
the makeup of this bar chart. The example consists of four GL
elements: bar charts, lines, boxes, and text.
2.
To determine the printable area of the paper, we printed a box using
0;0 as the x,y starting coordinates. This was done by typing
¬GB1;0;0;300;300;50 on the screen and sending it to the printer. The
top left corner of the printed box marks the top left corner of the
printable area of the page. For reference, we drew the printable area
on a blank sheet of paper. All references to distances are made in
respect to the printable page, not the actual physical page. Refer to
Figure 7-8.
3.
Determine where the chart should be placed (always in relation to the
top left-hand corner of the printable area). In the example, the bar
chart is on the bottom half of a letter-size page. The origin of the
chart is one inch away from the left margin and 10 inches away from
the top margin, as shown in Figure 7-19.
