A data visualisation system producing a contoured graphical representation of call centre activity

摘要

A data visualisation system comprises a finite set of discrete data values maintained in computer memory with each data value being associated with at least one time value and a display 200 configured to display a representation of each data value centred on respective data points. A contour generator generates and displays a contoured representation around each data point where each data point is displayed as a local maximum. Or the contour generator generates and displays one or more contour lines around each data point with each contour line representing data values which are less than the data value of the data point around which the contour line is displayed. The data visualisation system further comprises an interaction database maintained in computer memory of interaction data representing interactions between customers and merchants and a retrieval device configured to retrieve from the interaction database data representing interactions between customers and merchants, to construct the finite set of data values from the retrieved data and to store the data values in the data value memory.
