You are confusing the certification rules and how the OEM chooses to present the data to permit compliance with those rules. AFM/QRH presentation can vary from the old traditional British way of giving you each limitation on separate graphs through X-D composite formats to whatever sort of composite structure the OEM's aerodynamicists come up with when they are bored ... graphical, tabular, whatever ...
The QRH structures usually are very simplified to serve the purpose of the QRH ... quick data and assessment.
Generally, if you know what you are on about, it is not too difficult to replot etc to extract individual limits ... but it can take a bit of head scratching.
