From well known Redshift formula, we can draw a diagram about the Universe expansion.

Other factors, i.e., Doppler effect, etc. are ignored.

Your graph should have changed concavity again (sometime recently) because the expansion of the universe is accelerating at present.

To obtain correct expansion diagram, more exact Doppler effect estimation is needed.

The labelling "photon" in your first diagram is disturbing. IIRC the standard model does not state that the photon changed dimension over time.

But, after Inflation the model fits well.

And, other expansion cases are in this Figure.

This is a more detailed space expansion model.

This is a calculated result from the well known data.
