Abstract
An instrument for depicting change in the value of a first variable as a function of a second variable comprises a display device for displaying a set of n measured values distributed along a display axis, and a sampler for acquiring a set of N (greater than n) samples of the first variable and storing values of those N samples in ordered fashion relative to a first storage domain that maps to the second variable. A set of n display samples is selected from the set of N stored samples and the values of that set of n display samples are provided to the display device. When the set of n display samples is a set of samples that are at a predetermined spacing in the first storage domain and/or occupy a selected interval of the first storage domain, a set of N1 (greater than n) samples of the first variable are acquired and their values are stored in ordered fashion relative to a second storage domain that maps to the interval of the first storage domain.
