Initialize a bar graph in memory for later implementation. Graphs can be located anywhere on the screen, but
overlapping may cause distortion. Graph should be filled using the Draw Bar Graph command below.
ID
1 byte, unique bar identification number, between 0 and 15
Type
1 byte, graph style, see Table 27

Fill in a portion of a bar graph after initialization. Any old value will be overwritten by the new. Setting a value of
zero before setting a new value will restore a graph should it become corrupted.
ID
