Displays a bar graph (on a graphics page) at a specified AN. To scale a tag into the correct range, use the EngToGeneric() function.
Note: This function is only used for V3.xx and V4.xx animations, and was superseded in later releases.
Syntax
DspBar(nAN, Bar, Value)
nAN:
The AN where the bar graph will be displayed.
Bar:
The name of the bar graph to display in the format <[LibName.]BarName>. If you do not specify the library name, a bar graph from the Global library displays (if it exists). To display a Version 1.xx bar graph, specify the bar definition (1 to 255). For example, if you specify bar 1, Citect SCADA displays the bar graph Global.Bar001.
Value:
The value to display on the bar graph. The value needs to be from 0 to 32000 to give 0 to full-scale range on the bar.
Return Value
0 (zero) if successful, otherwise an error is returned.

/* Displays a value of 320 (that is 10%) on bar definition 3 (Citect SCADA Version 1.xx) at AN25. */
