Delete just three items from the right clic menu of a waveform graph

[CyGa]

I would like to delete some fonctionnalities from the right click menu of my waveform graph. If i use the specific function "delete menu", it works only if I want to delete all the right clic menu. But if I write the name of the specific item that i want to delete, this function returns an error.
What's happening?

I think you're trying to edit the default shortcut menu of an application item, which isn't allowed.  Another way to do this is to right click on the Graph->Advanced->Run-Time Shortcut menu->Edit
Select Custom and then add in any items to want to be displayed.  This easily creates a customized menu.
