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 expansion selection element positioned therebetween. The expansion element can be moved to various positions along the expansion bar, and the system responds by scaling each data analysis chart in accordance with the position of the expansion selection element. This allows the user to quickly re-scale each data analysis chart to the user's liking.
