which equates to an empty bar graph.
8. Click
OK
. The Bar Graph is displayed on the main screen of BlueLeaf. If necessary, use the mouse to
drag the object to the location on the screen that you want it. You can also highlight the object to
display the small white perimeter boxes and adjust the size. Simply move the mouse cursor over the
appropriate white box until the mouse cursor changes to a double-arrow symbol, then click and drag to
change the size.
Creating Analog Meters
The Analog Meter Object is used to represent the data in a 16-bit PLC register as a scaled meter. You can configure the
Display Meter in two styles:
300 degrees
360 degrees
Data in the PLC register can be interpreted as unsigned, signed, BCD, or hexadecimal. You can select the minimum and
maximum range displayed, then select the number of major delineations (tick marks) as well as minor delineations (minor
tick marks).
