Formula editor & parser

Hello Delphi and Builder-programmers,

I am looking for a library that can visually edit formulas (like the
formula-editors in WordPerect and Word) and are able to print the formulas
in a natural way.
The formulas should pe parsed too, to use them in a graphics program to
display graphs.

Is there anyting available?

Thanks for your reply,
