Chapter 11
Creating Bar Graph Screens
113
The bar graph can correspond to any range of values within the minimum
and maximum values stored in a register. In this way, you can present the
optimum control for an operator.
For example, if a register has values between 0 and 9999 that correspond to
-300°F to 1000°F. For register data, enter 0 and 9999 for the low and high
register limits, and -300°F and 1000°F for the display limits (the range
shown the operator). If the major region of interest for the bar graph were
100°F to 300°F, you would enter these limits and the bar graph will display
only the 100 ! 300°F range.

Note: Display and bar graph values can be scaled separately. Refer to the
description of scaling in Chapter 3.
