Add-On Graphics on reusable screens

This example depicts an Add-On Graphic with a mixer and a screen with additional mixer graphic elements. To have the screen and the Add-On Graphic on the screen show the values for the same mixer, bind the user-defined data type property that appears on an instance of the Add-On Graphic to the user-defined data type property of the screen. When a shortcut or navigation command passes a value into the user-defined property of the screen, graphic elements in the Add-On Graphic and on the screen show values from the same mixer. A Mixer1 shortcut or popup shows the values of Mixer1, and a Mixer2 shortcut or popup shows the values of Mixer2.
