Question with Microsoft Windows Graphing Calculator

[onu032001]

What Office Math Markup Language version does Microsoft Windows Graphing Calculator use?

Thanks for the question. I could not find any public documentation that specifies an OMML version for Windows Calculator’s graphing mode. The Calculator repo says the graphing UI is open source, but the graphing engine itself is proprietary and not included in the repo, so there is no documented OMML version I can point to.
