fx-9750giii vs fx-CG50

[lrdheat]

Due to the lack of a backlit screen, the 9750 giii is listed at ~240 hours on batteries vs ~100 hours on the fx-CG50.

I do wish that the data such as trace, roots, extremums were shown below the graphing screen. To avoid this, I set a window setting for the y axis such that the curser on an extremum especially, will not lie on top of the data (x,y value).

The CG50 does that nicely.
