Abstract

A data analysis computer system stores measurement data obtained from a multiplicity of distinct predefined processes. The system can store definitions for many data analysis charts, each of which depicts stored measurement data for a specified process. Further, chart groups can be defined. Each chart group comprises a set of data analysis charts that grouped together for convenient access. Charts are displayed by either (1) selecting a defined chart, or (2) by selecting a chart group and then selecting one or more charts from the selected group for, and then simultaneously displaying the selected data analysis charts. A data display gallery feature divides the computer system's display into a two dimensional array of cells, and assigns cell definitions to at least a subset of the cells. Each cell definition consists of either a set of measurement data which can be displayed as a unit, or a mathematical combination of a plurality of specified sets of measurement data. Typically each displayed cell contains a data map depicting a set of data in accordance with a corresponding cell definition. Each displayed data analysis chart is displayed with an expand bar having two ends and a ex…
