Go to this site and download GraphUp (formerly NGraph) by Harry Lotz &
Jutta - great replacement for the Borland graph unit - very powerful -
reqires a few changes to initgraph(much simpler) - supports just about
every gfx mode you can think of providing you have a Vesa compatible
Gfx card. 1024 x 768 no probelm - goes up to about 1800 x 1600. Works
in real mode - a protected/win mode is being worked on - free trial - a
few euros to buy - this is a great unit. English translation from
German (by me) a little shaky but you should be able to figure it out!
