GRAPH 3D v2.425 (20-FEB-2017)

First ensure that the app is properly installed. To check, press [Shift][Plot] to see if you can adjust the settings for Graph3D. If you do not see the proper settings then the application is likely not installed correctly. If you are in RPN mode, switch to algebraic mode. You may even want to test the installation on the virtual calculator. If it works on the emulator, then you can simply transfer the app from the emulator to the actual calculator.
