Nice! As an idea, maybe detecting the fixed-point to use before the actual graphing? Might get complicated, though...

Glad to hear it's faster. This will really be useful for math students if this gets finished. I think that could be worth a ticalc feature as well (although sadly it wouldn't be in Omni download section due to our game-only policies
) and one of the very few math programs to be featured.
It would be funny if teachers actually recommended this and even KOS if KOS included it
(TI would prbly be uber pissed)

That looks really cool. I thought you could do inequalities with the TI-OS though, I might be thinking of Piecewise Functions though. Though you could probably mix that and the shading thing together to get the desired effect (on the TI-OS). Only issue though is that the shading looks like crap on it (again, the TI-OS, I didn't mean you program, yours looks amazing
).

i can't believe nobody's ever made a gray grapher before(or maybe they have and i just havent seen it?). regardless, this shall be very useful.

I think one of the issue is that grayscale in ASM and BASIC (Doors CS/xLIB/Celtic/Omnicalc) can be hard to implement, while in Axe it's pretty much a joke

The hardest part gotta be in BASIC with 4 level grayscale. 3 level is not too bad but with 4 level you need to pre-render each frame of grayscale, meaning for a 8x8 sprite, for example, you need to manually draw the dithering and store each copy of the sprite in pictures. Not only in the end you got 4 pictures instead of 2 (including the one containing the black), but also it takes a ridiculous amount of effort to draw one single 8x8 sprite (about 30 minutes per sprite). Fortunately there is a tool to edit 4 and 5 level grayscale but it's still annoying because then you end up having to archive/unarchive stuff since the tool takes a lot of RAM (although you can use Doors CS)
