ABSTRACT:
A method and apparatus for dynamic variable scaling of spectral data utilizing the full available display area. Circuitry is provided to accept an initial upper scale limit. As a displayed data peak exceeds the initial preset limit, the maximum full scale limit is recomputed and the scale adjusted to accommodate the new data peaks on the full display area, each recomputation using as an upper scale limit a value slightly higher than the greatest peak value encountered. The method and apparatus may be utilized to vary dynamically each axis of a data display.
