When a bar graph is displayed, the last bar graph value transmitted to
the display is used (or the reference value after a reset). If a variable is
linked to the bar graph, it is also displayed accordingly.
When the display is cleared, the surface at which the bar graph is
displayed is overwritten with the current online background colour (from
the last “ESC-A” frame)! Black is used if the background colour has
been set to transparent! If a variable is linked to the bar graph, it is
cleared from the display as well.
Up to 255 bar graphs are possible (numbers 0 through 254).
The maximum variable length for linked variables is 127 characters.
