Transformation from A to B frame problems

asked 2021-03-02 10:58:26 -0500

I decide to transform from A frame to B frame by translation 1 m and rotate 90 degrees。 I decided A to be my fixed frame so I thought that A should also set to be parent frame and B is a child friend. The rqr_tf_tree seems correct. However, the frames show on rviz really confused me. I wonder why the arrow points toward A frame instead of B frame. I thought that the arrow should point toward B frame so it means transform from A frame to B frame.
