what's the term for “tone contour”? I would like a translation in putonghua for “tone contour” as in “the tone contour of 普通话 is 314”

I found two terms:


声调轮廓 from CC-CEDICT 
音调曲线 from ABC dictionary


Are either (or both?) of these what I'm looking for?
Only the first one is correct (聲調輪廓), as a jargon used in linguistics. The second one is a (bad) word-for-word translation of tone (音調) + contour (曲綫).
