Each symbol can have up to four different states. Unique attributes can be
assigned to each state. You assign a PLC address (1 – 3 bits) to control
these states. The value of these bits determines which state attributes are in
effect (color, blink, intensity, etc.).

If the value is less than zero, then state 0 will be displayed. If the value is
greater than state 3, then state 3 will be displayed.

IMPORTANT: All bits off displays state 0.

Bar graphs can be used to monitor changing conditions, such as
temperature or fluid levels. You can create vertical and horizontal bar
graphs up to 80 characters wide and 24 characters high.

Vertical bars move from top to bottom. Horizontal bars move from left to
right.

On the PanelView terminal, bar graphs will operate at pixel resolution.
Each character cell is 8 w x 10 h pixels.

You can use Outer Text to make incremental marks alongside the bar
graph. The underscore character often does this best for vertical graphs.
