If you have selected several different objects, e.g. data sets and formulas in the object list or curves or axes in a diagram, you can show or hide properties that are not common to all objects:
•Select the option Show Only Common Properties from the Properties window toolbar to hide these properties, or uncheck the option to show them.
Note: Properties that occur in several objects and that have different content are displayed with an empty edit box. If you edit this type of property, then this change will affect all selected objects.
