paused and the scale of the X and Y axes can be changed via a tool bar
located in the top right corner of the Serial Grapher Application.
All data to be displayed must be in hexadecimal format. The data can be
accepted and displayed either as incoming byte values ($00-$FF) or word
values ($0000-$FFFF). The data format indicates whether the data is byte or
word data. The graphical components automatically size their range
depending upon the incoming data.
This PC-based application is included on the DVD-ROM that accompanies
the DEMOEM and may also be found at:

The Bar Graph has four separate bars A, B, C, and D. On each bar a
percentage value is displayed which indicates the current value relative to the
full range. A byte value of $7F (max is $FF) would show up as approximately
50% as would a word value of $7FFF (max is $FFFF). As can be seen in the
data formatting section, all four bars must be written at the same time. The
bars are shown here:
