Plot Data Format
You must define each byte for a complete line of data in plot format. Plot Data

Plot Data Byte Format
Each data byte specifies six of the twelve dot columns that compose one
character column. Using odd dot plot, bits 1 through 6 of the data byte
address the odd numbered dot columns; using even dot plot, bits 1 through 6
of the data byte address the even numbered dot columns.
character column. Using odd dot plot, bits 1 through 6 of the data byte
address the odd numbered dot columns; using even dot plot, bits 1 through 6
of the data byte address the even numbered dot columns.
A dot is printed for each bit that is set ("1") in the data byte. When using plot
commands, bits 7 and 8 of the data byte must
commands, bits 7 and 8 of the data byte must
always be set "1". The sum of
each bit in the data byte, in hexadecimal value, becomes the plot data used in
the plot command.
the plot command.
For example, refer to Table 17. A hex data value of C4 prints a dot at the
column corresponding to the 04 bit. A hex data byte value of FF produces
dots in all columns; a value of C0 leaves the column blank. The bit pattern
addresses the odd columns of the character space for odd dot plot or the
even columns of the character space for even dot plot. Both odd and even
columns are used for high density plot. These hex data bytes to produce the
graphics pattern are entered in the data parameter of the plot command.
Table 17 illustrates the plotting hex data required to produce the same arrow
