Unity3d scene doesn’t show X and Y axis for my selected object

Introduction

I have 2d objects in my 2d project. I select one of them, the unity3d scene does not show the X and Y axis. It only shows the boundingbox of my selected object as following.

Solution

This is because my Object is a UI Object and I am in RectTransform mode since UI Objects use the RectTransform instead of just Transform. solve by chaning the model like below
