Initialize Thin Bar Vertical Graph

ASCII 's', Hex 73, Decimal 115

Syntax 0xFE 0x73

This command is executed in exactly the same manner as the 'Initialize Thick Bar Graph' command.

Make Vertical Bar Graph

ASCII '=', Hex 3D, Decimal 61

Syntax 0xFE 0x3D

This command places a bar graph at the specified column with the specified height. The style of the vertical bar graph

whether it be thick or thin is selected by the initialize vertical bar graph command. If thick bar graphs are preferred, the 'v'

command should be send to initialize the bar graph. If a thin vertical bar graph is desired, the 's' command should be sent.

The format for the command is as follows:

0xFE

0x3D

0x01 to 0x14 for an twenty column display

0x00 to 0x16 for a two line display.

Bar height is in pixel widths. On a two line display the maximum bar graph height is sixteen, this is because each of the

lines in the display are eight pixels high. The width of the space between the lines is not taken into account.

Note: Vertical bar graphs may not be used with horizontal bar graphs, and thick bar graphs may not be used with thin
bar graphs. This is because all these functions make use of the same "custom character" spaces. As a result, custom
characters are also unavailable while any of these functions are in use.
