The GPSA manual has the best one I know of. Perry's and perhaps the ASHRAE handbooks might have them but they are typically a lot smaller and harder to read values off of.
You might also check with any compressor vendors. I would suspect they have mollier diagrams for methane available.

The most authoritative and recognized source for complete Methane Thermodynamic data is no other than our USA government:
--and it is FREE, since our tax dollars have paid for it. It gives you excellent, detailed, and down-loadable tabular data that drops right into Excel. Granted, it's not in the form of an impressive (& inaccurate) Mollier diagram, but it detailed, thorough, and as recognized as anything you can obtain to back-up official and legal engineering calculations. I think more than one forum member has found this out already. The NIST gives complete, free information on 34 compounds in their database. This should certainly fill your engineering need - if Methane (rather than Natural Gas) properties will do.

Tom:
I just clicked on the Hyperlink and I was taken directly to the NIST website where you will find the first drop-down box for information called:
"1. Please select the species of interest:"
You drop the menu down and select "Methane". Presto! You now have to fill in the information about Methane that you would like!
I don't know what the problem is with your attempt, but it should work - just like mine did when I clicked on the Hyperlink in my post.
I know it works and you're the first person to have trouble with my hyperlink and instructions. Please try again; I guarantee it works!
