1. In the Call Graph, select the method you want to remove from the current dataset, together with its descendants, but whose memory data you want to retain.
2. Right-click in the window and select Subtree > Hide Subtree. Purify removes the subtree from the dataset, but retains the memory data in the method + descendants (M+D) bytes of the callers.
Notes:
§ To restore the hidden subtree, right-click in the Call Graph and select Subtree > Undo Hide Subtree from the shortcut menu. If you have focused on or deleted other subtrees in the meantime, you must undo those operations first.
§ To reset the current focus to .Root., select Subtree > Reset to .Root. from the shortcut menu. Purify undoes all subtree operations and redisplays .Root. and its top 20 descendants by method + descendants (M+D) bytes).
