Pleeese!! plot software for Phase Diagram of 3-Components.

 To Netter!!!
 Happy New Year!!
 This is my first posting.
 But  I am sorry for my asking the simple questions.
 I want to plot for Phase Diagram of 3-Components,
  because I should insert  this plotting  in my paper.
 This is very emergent problem.
 So, Pleeese!!
 I want to get plot-software or methods for Phase Diagram of 3-Components.
 Thanks a lots....
