Feature Description
The significance of managing chart groups lies in improving chart browsing and query efficiency. By consolidating multiple non-editable chart groups into a single collection, unified management of multiple groups can be achieved while avoiding redundant datasets. For example, when a chart group contains feature objects like anchorage areas, navigation marks, and depth contours, merging multiple groups allows these features' class datasets to form a union set, eliminating data duplication and enhancing both data consistency and management efficiency.
Steps
Create Non-editable Chart Group Collections
- In the Workspace Manager, right-click the Chart node under the datasource and select New Dataset... -> Non-editable Chart Group Collection... from the menu.
Or go to the Chart Tab -> Chart Data Management group -> Click the New Group drop-down button -> Select Non-editable Chart Group Collection.... This will open the Create Non-editable Chart Group Collections dialog.

Manage Non-editable Chart Groups
- In the Workspace Manager, right-click the newly created non-editable chart group collection node and select Manage... from the menu to open the Manage Non-editable Groups dialog.
