Description This command initializes a bar graph referred to by number [reference

number] of type [type] with size from (x1,y1) (top left) to (x2,y2)

(bottom right). A maximum of 16 bar graphs with reference numbers

from 0 to 15 can be initialized as:

[type] Direction Bar Start Point

0 Vertical Bottom

1 Horizontal Left

2 Vertical Top

3 Horizontal Right

The bar graphs may be located anywhere on the display, but if

they overlap, they will not display properly.

It is important that [x1] is less than [x2], and [y1] is less than [y2]. This

command doesn’t actually draw the graph, it must be ﬁlled in using the

Fill Bar Graph command. The unit saves time by only drawing that part

of the bar graph which has changed from the last write, so the represen-

tation on the screen may not survive a screen clear or other corrupting

action. A write of value zero, followed by new values will restore the

proper look of the bar graph.

number to ﬁll in [value]. [value] is given in pixels and should not
