The percent of symbol keyword is added to a Value in a List clause to specify that the size of an analytic depiction should be displayed at a certain percentage of its associated symbol’s size on a diagram. Alternatively, you can specify that the analytic depiction symbol size is fixed, or not specify anything at all.
Example
The following example displays the .WMF files at 50 percent of the size of a Node symbol in a Deployment diagram:
List "Traffic Lights" percent of symbol 50 { Value "None" Value "Red" depictions {right images\redlight.wmf} Value "Yellow" depictions {right images\yellowlight.wmf} Value "Green" depictions {right images\greenlight.wmf} } SYMBOL "Node" In "Deployment" { PROPERTY "Analytic Traffic Light" { EDIT Text List "Traffic Lights" DEFAULT "None" LENGTH 10} }
