Using a graphic layer, I am attempting to create a graduated symbol in XAML. The symbol has a number (text box) within it which is data bound (through XAML) to an attribute of the graphic. This number is displayed correctly. The height and width of the symbol is data bound (through XAML) to an attribute of the graphic; when the number is larger the symbol is to be larger. This is working but the center of the symbol is not in the correct location.
What is the proper way to ensure that as the size increases, the circular symbol expands from the center outward? Right now the size is increasing outward from the upper left. I am unable to set the XY offset as the symbol size is to change dynamically.
