altimeter calibration

Early this year I started a discussion on another forum asking what might cause a discrepancy between altitude calculated from radalt plus ground elevation, and altitude as shown by an altimeter, correctly set on local barometric conditions. The plane in question, a Boeing 757, was travelling at very high speed at low altitude. The consensus was that radalt would not be affected by high speed but the altimeter would likely be out of its calibration envelope.

I have been told that there is a graph in the flight manual which shows errors that would be encountered under various flight conditions. Is there any way to get hold of this graph?
