Feature req: comparison

Open paulirish opened this issue 2 years ago • 3 comments

https://chromedevtools.github.io/timeline-viewer/ has comparison functionality. (Click the 'split view' link, then dragndrop in your traces). It also synchronizes the zoomed timescale across the split, making for even comparison. (At least, it sync's when you brush-select on the overview, though not other zoom gestures)

It'd be great to have similar functionality here. But since CDT is in an iframe, it's going to be a different story than the monkeypatch injection I did in timeline-viewer.

Perhaps with a conservative postMessage protocol, CDT and t.c can coordinate... 🤔

Wow I would love that functionality! I usually use two windows and drag and drop (I've missed that it was implemented in timeline-viewer).

+1, I would love comparison of two trace.cafe traces as well if possible.

It would be widely helpful in the context of INP before/after comparison (screenshot and Tasks difference).
