That doesn't look like dyna graph.  This looks like its the regular graph mode with several inequality equations.  The shading for these graphs overlap causing a dithering pattern that results in those extra colors.

I've been working on making a program to demonstrate the abilities of graphs and how they can be used used in programs, but I still can't get the syntax right for changing the color of graphs. Otherwise I have every other function that I wanted to demonstrate in place. One way to draw graphs smoothly in a game is to use the command SimulOn which causes every graph to be drawn at the same time instead of separately.

Would this help? http://ourl.ca/9185/174354

Yeah I remember that. Anyway one idea I had for example would be if the Prizm supports X=, we could use 4 lines to form dungeon walls or something, although in some cases it might not be super practical, plus it would be slow.

There is x= but I need to check if you can draw y= and x= at the same time.

It's possible. I tried drawing one line at every edge of the screen... It worked, but the colors made it look all rainbow-y

EDIT: Somehow the entire problem vanishes once I replace PlotOn with PxlChg. I don't know how, but it works.

I have a problem with the PxlTest command in an IF statement. I basically want a dot to move around the screen without running into any pixels that are on. But for some reason the dot will move regardless of whether or not there is a dot in the way. I used a different program to check it by breaking the program when the dot is next to a pixel in the on state, and it says it is on, no matter how i formulate it (PxlTest(B,A), PxlTest(B,A)=0, PxlTest(B,A)=/=1, etc) it will definitely say the pixel is on. But the IF-statement will simply ignore whatever state the pixel is in. I'll post the code for the IF-statement when the down button is pressed.

If Getkey=28 And PxlTest(64-B+1)=0
(the 64 is because I use PlotOn to place the pixel, making the Y-coordinate (the B variable in this case) inverted. Because the graph screen is 64 high this makes sure the coordinates are correct)
Then A->D:B->E:B+1->B
(D and E just remove the old dot image when it has moved)
IfEnd

If you think it's the inversion making it go wrong it isn't; as I said before I tested it by continuously using PxlChg on the pixel that should be tested to make sure the right pixel is tested. Can anybody help me?

great guys.. got some idea.. really big help.. wait i will fix mine..
