How to control the drawing level of QCPAbstractItemReturn to overview

Different types of QCPAbstractItem will cover each other, I want to control their drawing level or drawing order (the order of creation in the scene can not be controlled) How do I change? Or are there other ideas? Thank you

This is done with layers, have a look at the documentation
