y+ values

Hi all, I am a beginner CFD user and I am doing an 3D model exercise of air passing near a wall. I had a look of the y+ values in order to know what those values are. I am using k-e method. I created a plane with y+ variable finding that the y+ value of nearer cell from the wall has a a value of 2.2. However, while the distance is further from the wall y+ value is decreasing to 0. I thought that y+ were higher as its measure is done farther from wall. I attached an image. I appreciate any insight about this. Thank you.
