Once you get the O2 sensors changed out graph the readings again.
But take it for a drive first so your sure the Cats are hot.
Graph them with the RPM's held around 2000-2500.
Your post cat graph lines should look much like the screen shots you posted.
but in the .450v range.
The 1.00v-1.06v in your screen shots seems out of range to me.
But they were tested at idle just after cold start.
But your changing them out so not important at this point.
