Looks like they are doing what they should. The upstream (#1) sensor should be bouncing up and down like it is and the downstream (#2) sensor should remain pretty level like it is.

I'm not 100% on the numbers that #1 should be bouncing between but again it looks fine. If it was steady, then you'd have issues.
