To delete a Custom Data set:
| 1. | Select Data→Save/Load→Custom Data→Delete. An entry will appear to the right for each set of custom data that is defined. | 
| 2. | Choose the Custom Data set to delete. You will not be prompted to confirm your choice. If you want to immediately restore a custom data set that was deleted by mistake, use the Undo command in the Quick Access Toolbar. | 
Alternatively, right-click on the custom data set in the Data Navigator and choose Delete from the pop-up menu, or highlight your custom data and press Delete on your keyboard.
