Enthalpy diagram?

What if I asked this: "Can someone tell me whether a price diagram has two axis?"

That of course makes not sense, nor does your question. When you say diagram, you have to be much more specific. Enthalpy versus what...time?...temperature?...mass?

Because all of these are on a flat screen, they are two dimentional. https://www.google.com/search?q=enthalpy+diagram&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
