Abstract
Abstract Digitally represented desired and actual value series are plotted in graph form on a television screen for the purpose of comparison. The corresponding desired and actual values are shown in the same line of the picture so that the desired value curve and the actual value curve extend parallel to one another. In order to be able to predict the future course of the actual value curve, the desired value curve runs across the entire screen, while the actual value curve extends only across a part thereof. The most recent actual values are shown in a midportion of the screen. In this manner, desired values are shown for which no corresponding actual values are yet available.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A method of comparing digitally presented actual and desired values, comprising the steps of A. displaying a series of desired values as a curve extending across the entire field of a television screen, B. displaying a series of actual values as a curve extending solely across one part of said field, C. adding the newest actual values to the actual display of the value curve at a midportion of said field and D. orienting the respective curves so that mutually corresponding actual and desired values are displayed in the same and-raster line of the television picture.
Claim 2
Independent Claim
96 words
A method of comparing digitally presented actual and desired values, comprising the steps of A. displaying a series of desired values as a curve extending across the entire field of a television screen, B. displaying a series of actual values as a curve extending solely across one part of said field, C. adding the newest actual values to the actual display of the value curve at a midportion of said field and D. orienting the respective curves so that mutually corresponding actual and desired values are displayed in the same and-raster line of the television picture.
Claim 3
Dependent Claim
186 words
A method as defined in claim 1, including the steps of A. inscribing, at the beginning of curve representation, the desired values and the actual values in two separate and similar image repeating memories; mutually corresponding actual and desired values are inscribed in memory cells with the same address, B. cyclically applying said actual and desired values from said image repeating memories to a video apparatus including said television screen, C. subsequently inscribing a predetermined amount of desired values in the image repeating memory for desired values, D. shifting the actual values in said image repeating actual value memory with respect to the addresses by the same amount and extinguishing the same amount of actual values inscribed therein substantially contemporaneously with said step of subsequently inscribing, E. shifting the stored actual and desired values by one memory location for inscribing new actual and desired values, F. inscribing the new desired value in the vacated memory location with the lowest address and G. inscribing the new actual value in the vacated memory location with an address higher than that assigned to the previous most recent actual value.

Dependent Claim
210 words

E. shifting the stored actual and desired values by one memory location for inscribing new actual and desired values, F. inscribing the new desired value in the vacated memory location with the lowest address, G. inscribing the new actual value in the vacated memory location with an address higher than that assigned to the previous most recent actual value, H. counting by means of a shift counter and without a simultaneous inscription of actual values in the image repeating memory for actual values the number of desired values introduced into the image repeating memory for the desired values, I. comparing the contents of said shift counter with the contents of a line counter and J. beginning the representation of the actual values when identity between the contents of said shift counter and said line counter is reached.
