  • Abstract
    Utilization of the three-dimensional aspects of the cathode-ray tube¿vertical signal deflection, flexible time base, and intensity modulation¿makes it possible to organize certain types of data into a meaningful format, greatly simplifying the interpretation of these data. This article describes the basic principles of organizing and displaying data in the contouro-graphic form, indicates several degrees of complexity in providing the instrumentation for this method, and presents a number of contourograms illustrating various applications.
