# Proportional Hazards Assumption - Schoenfeld Residuals X-Axis

I am testing the PH assumption for my COX PH model. Can someone describe what the two x-axis's are in the Schoenfield Residuals plots? One is rank-transformed time and the other is km-transformed time. How do I interpret these transformations (I'm not sure what these are practically)?

My response term here can range from counts of 1,000 to 30,000,000. Is this suggesting that within 150 (time counts), the coefficient increases to zero from ~ -1.0?
