Happy to merge the first 3 commits; but the last two seem to be one-off tests.

Thanks for your reply~

I don't quite understand the words one-off tests (not use the PR quite often...), could u explain it a bit?

Does that mean I should close this PR and create another one which contains only the first 3 commits?

BTW, I have one more question on the dimlist parameter of Graph (#140 (comment)). Could you take some time to answer it?

Thank you very much~~~~ :-)
