Unlinking from a master visualization
Unlink a visualization from its master visualization to edit only the current instance. Unlinking removes the connection between the visualization on your sheet and the master item. The current visualization becomes independent. To edit all visualizations that are linked to a master visualization, see Editing a master visualization.
Do the following:
Click Edit sheet.
Click in the top right corner of a linked visualization, and then click Unlink visualization.
A dialog is displayed that you are about to unlink from a master visualization.
The visualization on the sheet can now be edited and the changes will not affect any other visualizations.
