Analysis combination for large data quantities - uses trend curves and event references for checking economic processes

摘要

The trend curves and event references of the analysis combination are represented on a common simple logarithmic unit scale. A calculating rule is used on the same unit scale in order to analyse the curves. This calculating rule is employed to read correctly in time the measured values, relations, growth rates and event references. The calculating rule consists of transparent material having one or more scales which are logarithmic in a longitudinal direction and linear in a transverse direction.
