System for displaying evolution of one physical parameter compared with development of another physical parameter

摘要

The invention relates to a process and a system for the display of time-variable quantities.PPThe system comprises a computer, a memory for recording the values of the quantities, a clock, acquisition means for the values of the quantities, connected to the computer, as well as display means connected to the computer. The system also comprises means for simultaneously recording in the computer memory and at the same acquisition frequency, the development of the values of one of these quantities compared with the development of the values of the other of said quantities, or the development of the values of one of these quantities compared with the development of the values of the other of these quantities as a function of time, the computer controlling the display means in order to obtain the image of the graph or graphs representing said development or developments.PP Application to the display of the development of values of physical quantities.
