The Data wizard allows you to modify the
data on which a diagram is based. The styling rules set for the
diagram are not affected by the changes.
To open the Data wizard, go to Diagram Editing mode and choose Data>Edit Model.
The Data wizard has the following pages:
Welcome
Edit
Your Data Model
Add and
remove rows, where each row represents an object in the model.
Add,
remove, and rename columns, where each column represents a
property in the model.
Modify
property values.
When modifying the data model, be aware that
model properties may already be used in the style rules defined for
the diagram. If you change a property name, the affected style
rules may become inconsistent. Therefore, when you try to remove or
rename a property, a warning message will be displayed indicating
the style rules that will be affected by the operation, if any. In
case you need to rename a property, the preferred path is to create
the new property and modify the style rules to depend on this new
property. Once this is done, you can safely remove the previous
property using the Data wizard.
