THAT was my point.

My point was that Cartesian plane in HP Prime is not perfectly implemented and I have asked only confirmation for unexpected numbers, on which Tim elaborated clearly. As well, It is not at all difficult (as you presented) to use directly screen coordinate system. I used similar approaches with any graphical application I have made in my professional carrier (If needed Cartesian plane) and there is no much difference where is the coordinate center on the screen as translation is trivial in any case...

I will be more specific in the future or send the noted issue directly to HP.
Thank you.
