Phase diagram/open element capability?

Hi all: I use the MP extensively in my teaching and I find your phase diagram tools to be particularly useful. However, it seems I can no longer draw phase diagrams with an “open element” like I used to. Is this capability still available, and if so, how can I access it?


Thanks for bringing this up. The “open element” feature is indeed not available in our new website. We’re discussing internally whether to bring it back. For now, you can still access the legacy version of our website through (though the underlying data are not updated anymore).
