Xmin=0
Xmax=126
Ymin=-1
Ymax=1
This gives a straight line. This proofes that te calculator really draws the function in a to small screen. Why?

Why not use al pixels for dwawing graphs? The screen has a resolution of 64*128. But why draws my calculator functions in al 127*63 screen? Is er a reason for this. I've tested this whit te function y=sin(2pi:1)X in:

While the AFX_Master is getting his AFX, I tried it out on my Algebra FX 2.0 Plus. It produces the same outcome. Also my fx-9860 draws only to 127x63 screen.
I don't know why it does that, it may have to do with memory. Anyways, it's not really such a big problem, you can scroll the ViewWindow to see other parts of the graph.

Viewwindow -6.3,6.3,.1 ...
I think that is the default setting of ViewWindow on the FX (after the fx-7xxx series), CFX series and the Algebra FX.

0 : 1 pixel
0.1 to 6.3 : 63 pixels
total : 127 pixels

Of course, my fault, I am used to think about 0 as a interval, so I [0,1] is one pixel.
