Hello,
You can modify the view of functions in diagram by right-clicking then selecting "view as icon". Nevertheless,this option is only available for VI express and standard functions. Standard functions are functions which have this own diagram and front-panel. You cant expand simple arithmetic functions such as multiply.
Moreover, you need LabVIEW 7 to use this option (view as icon).
Hope this help.
