CHAPTER 7: Advanced Features
The bar representing Boyd’s calls for Tuesday was to be printed one inch to
the right of Monday’s bar. The resulting <x-increment> was 300 (x
1
⁄
300
" =
1"). Since the maximum height of a bar was specified at four inches, the
resulting value for the <y-increment> was 30 (x 40 max. calls x
1
⁄
300
" = 4").
To aid in readability, extra space was left between the last bar of day one
and the first bar of the next day. To determine the <bar width>, divide the
available one inch (<x-increment>) into four equal sections (three bars
and one space). The resulting value was 75 (= 300 ÷ 4). Next, count the <#
of entries> (5) and enter the respective values. The parameters are:
¬GX'bar chart Boyd'
¬GS5;01;10;01;10;01;10;01;10;01;10
¬GH1;300;3000;300;30;75;5;30;34;39;37;28
Bar Chart—Gary
The bars representing Gary’s calls were to be printed directly to the right
of Boyd’s. The resulting horizontal start value <x start> was:
300
(Boyd’s)
+ 75
(Bar width)
375
With the exception of the actual calls, the other parameters for Gary’s bar
chart were identical to Boyd’s. The parameters are:
¬GX'bar chart Gary'
¬GS5;02;75;02;75;02;75;02;75;02;75
¬GH1;375;3000;300;30;75;5;35;36;38;39;31
