Dear Nena,
you can use the
SET_ATTR_VAL method to set/change the value of an attribute via AdoScript. Thus, e.g. to change the background color of an object you can create an attribute for the color and use the value of this attribute in the GraphRep code. Consequently, every time you change the value of the attribute using AdoScript (
SET_ATTR_VAL method) the graphical representation of the object will also change (or in this case the color of the object).
