Runtime behavior of the Show/Hide Graphic functions

The Show/Hide Graphic script functions exhibit the following behavior:
-
The graphic, configured with the ShowGraphic script function, behaves like a ShowSymbol animation pop-up window, rather than a typical HMI pop-up window.
-
You can configure a graphic with both the ShowAnimation and ShowGraphic scripts together. If you execute the two scripts at runtime, two pop-up windows open, displaying the same or different graphics. The two pop-up windows are independent of each other.
-
You can open, close, and manage the graphic from across graphics and across the entire HMI application.
-
Unlike ShowSymbol animation, there is no parent/child relationship between the window that launched the graphic and the graphic launched by the ShowGraphic() script function. For more information, see Closing a graphic.
-
You cannot use the Close Window dialog box or similar dialog provided by your HMI/SCADA software at run time to close the pop-up windows displayed by the ShowGraphic script function. For more information, see Closing a graphic.
-
Any graphic displayed by ShowGraphic script function or ShowSymbol animation always remains in front of HMI application run-time windows, except pop-up windows that might be supported by your HMI/SCADA software. Even if you click a run-time HMI window, the window remains behind these graphics.
-
If your HMI/SCADA software supports memory caching, enabling in-memory graphics caching in HMI run-time memory properties will keep ShowGraphic and ShowSymbol animation popup graphics cached in memory. The system tracks the order in which graphics are closed in order to determine their age. If a user-defined in-memory limit is exceeded, the system automatically removes the oldest popup graphics in the in-memory graphics cache except those defined in high-priority windows. If you display a graphic with the ShowGraphic script function or with ShowSymbol animation, the HMI run time will perform a memory health check if supported by your HMI/SCADA software.
