Hi Harry,
The best way to toggle data depiction is with:
DataRenderer.toggle(boolean)
As for bulk adding and removing of references, you can remove them all with:
DisplayImpl.removeAllReferences()
Add multiple references at once with:
DisplayImpl.addReferences(DataRenderer, DataReference[])
or:
DisplayImpl.addReferences(DataRenderer, DataReference[], ConstantMap[][])
But hopefully you won't need to add or remove massive numbers of references
over and over, since DataRenderer.toggle() is much faster.
