When I add X-Y data from a spreadsheet into 10.2.2, the points do not plot correctly. I followed the steps in the knowledge base article (27589), and have tried projecting, reprojecting, using an existing layer as the coordinate system, changing from one coordinate system to another and back, and starting with a blank map - which plots the points correctly, but sends anything I add to another location. I am using NAD 83 State Plane 4203. The area where the points should plot is around 30 N, -103 W, but they plot at 3N, -105 W.
I converted the coordinates to numbers to 8 decimal places. I tried with both csv and xlsx spreadsheets. Anyone have any ideas?
