Make Horizontal Bar Graph
ASCII '|', Hex 7C, Decimal 124
Syntax 0xFE 0x7C<column number><row number><direction><bar length>
This command places a horizontal bar graph at the specified column and row with the specified width. The format of the
command is as follows:
<command prefix > 0xFE
<command> 0x7C
<column number> 0x01 to 0x14 for a twenty column display
<row number> 0x01 to 0x02 for a two line display
<direction> 0 for left to right, 1 for right to left
<bar length> 0x00 to 0x64 (0 to 100) for a twenty column display
Bar length is in pixel widths. On a twenty column display the maximum bar graph width is one hundred (if the bar graph
starts at the edge). This is due to the fact that each of the twenty columns on the display are five pixels wide. The width of
the space between columns is not taken into account.
Initialize Thick Vertical Bar Graph
ASCII 'v', Hex 76, Decimal 118
Syntax 0xFE 0x76
Before any thick vertical bar graphs may be created, this command must be executed. It only needs to be sent once to
initialize the custom characters required for bar graph creation. Bar graphs use custom characters, therefore no user
custom characters may be displayed or created while bar graphs are in use.
Initialize Thin Bar Vertical Graph
ASCII 's', Hex 73, Decimal 115
Syntax 0xFE 0x73
This command is excuted in exactly the same manner as the 'Initialize Thick Bar Graph' command.
Make Vertical Bar Graph
ASCII '=', Hex 3D, Decimal 61
Syntax 0xFE 0x3D<column number><bar length>
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 to
initialize the bar graph. The format for the command is as follows:
<command prefix> 0xFE
<command> 0x3D
<column number> 0x01 to 0x14 for an twenty column display
<bar length> 0x00 to 0x20 (1 to 32) 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.
