Menu: View→Object Properties→Visibility→Show parameters
Uncheck this box to hide any parameters associated with a rectangle, ellipse or arrow. The state of this box has no effect on the display of variable names, rectangles, ellipses or arrows.
Note: When the Use visibility settings box is unchecked, the state of the Show parameters box is ignored -- no parts of the path diagram are hidden.
