Displaying a bargraph means to show the last sent value (which is equal
to the reference value after RESET). If a variable is connected to the
bargraph then it will be displayed, too.
Clearing a bargraph means to fill the bargraph area with the current
online background colour (from the last „ESC-A“ frame). „Black“ is used
if the online background colour has been set to „transparent“! If a
variable is connected to the bargraph then it will be cleared, too.
At the moment no more than 255 bargraphs (numbers 0 to 254) are
allowed.
Each connected variable may have a maximum number of 127
characters.
