I read about Collatz conjecture a few weeks ago and have made a few programs for printing out various stats, but I want to make a prog that can make a graph similar to
[img]http://upload.wikimedia.org/wikipedia/commons/b/b9/Collatz-stopping-time.svg[/img]. What should I use, and how what functions should I look up? I'm really only looking for a way to make a simple 2d graph that can be dynamically updated as I find stopping times for different numbers.

That's a 2D graph. Use native win32 api functions or a 2D library such as Cairo.

To setup Win32::OpenGL and plot a pixel in FASM...

Ok, so here is very basic way to use GDI to set pixel color...
Code:

format PE GUI 4.0
entry WinMain

include 'WIN32A.INC'

section '.code' code readable executable

   WinMain:

        invoke  GetModuleHandle,NULL
        mov     [wndclass.hInstance],eax
        invoke  LoadIcon,0,IDI_APPLICATION
        mov     [wndclass.hIcon],eax
        invoke  LoadCursor,NULL,IDC_ARROW
        mov     [wndclass.hCursor],eax
        invoke  RegisterClassEx,wndclass

        invoke  CreateWindowEx,WS_EX_OVERLAPPEDWINDOW,szAppName,szAppName,\
                  WS_OVERLAPPEDWINDOW+WS_VISIBLE,CW_USEDEFAULT,CW_USEDEFAULT,\
                  CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,[wndclass.hInstance],NULL

  .mainloop:
        invoke  GetMessage,msg,NULL,0,0
        cmp     eax,0
        jle     .finished
        invoke  TranslateMessage,msg
        invoke  DispatchMessage,msg
        jmp     .mainloop

  .finished:
        invoke  ExitProcess,[msg.wParam]

proc WindowProc hwnd,umsg,wparam,lparam
  local ps:PAINTSTRUCT
        mov     eax,[umsg]
        cmp     eax,WM_PAINT
        je      .wmpaint
        cmp     eax,WM_DESTROY
        je      .wmdestroy
  .defwndproc:
        invoke  DefWindowProc,[hwnd],[umsg],[wparam],[lparam]
        jmp     .finish
  .wmpaint:
        lea     eax,[ps]
        invoke  BeginPaint,[hwnd],eax
        invoke  SetPixel,[ps.hdc],10,10,0x00000000 ; paint black pixel at [x,y]
        lea     eax,[ps]
        invoke  EndPaint,[hwnd],eax
        jmp     .zfinish
  .wmdestroy:
        invoke  PostQuitMessage,0
  .zfinish:
        xor     eax,eax
  .finish:
        ret
endp

section '.data' data readable writeable

  szAppName db 'dib',0

  wndclass WNDCLASSEX sizeof.WNDCLASSEX,CS_OWNDC,WindowProc,\
    0,0,NULL,NULL,NULL,(COLOR_WINDOW+1),NULL,szAppName,NULL

  msg MSG

section '.idata' import data readable

  library kernel32,'KERNEL32.DLL',\
          user32,'USER32.DLL',\
          gdi32,'GDI32.DLL'

  include 'API\KERNEL32.INC'
  include 'API\USER32.INC'
  include 'API\GDI32.INC'
