Abstract: A system and method for gathering and displaying information in data intensive environments. It is particularly concerned with data analysis in a critical care environment to provide a graphical display of derived information, comprising a series of bar charts (a-h) representative of a corresponding series of functions (32). Each bar chart comprises a linear series of time-divided segments (34) wherein each segment (34) of each bar chart (a-h) is assigned a colour corresponding to the status of that function (32). The status of each function (32) is derived by scoring contributory data indicators in accordance with pre-set threshold values, and logically combining to produce a status score for each function. Interventions that affect particular functions may also be recorded and displayed against those functions so that their effect is readily discernible.
