1. A method, comprising: generating at least one display output using at least one computer from multi-parameter N-dimensional data, wherein data dimensions are indexed by one of (a) three index pseudo-dimensions or (b) two index pseudo-dimensions and one time dimension, the display output depicting volumetric data spaces selected from C N M = N ! M ! ⁢ ( N - M ) ! possible ways to depict multi-parameter data with M-dimensional data spaces, said possible ways comprising at least one of (i) three mutually perpendicular axes comprising a time axis and two index pseudo-dimension axes, or (ii) a time sequence of volumetric data spaces with three index pseudo-dimension axes; generating, in response to user input selecting higher-order volumetric data space, a display output depicting the higher-order volumetric data space having three mutually perpendicular axes comprising three index pseudo-dimension axes or a time axis and two index pseudo-dimension axes; generating, in response to user input selecting lower-order volumetric data space and a data point along one of the mutually perpendicular index pseudo-dimension axes, a display output depicting the lower-order volumetric data space having three mutually perpendicular axes comprising three index pseudo-dimension axes or a time axis and two index pseudo-dimension axes; and generating, in response to user input selecting at least one of a point in time, a point on index pseudo-dimension axis, or a set of data sets, a display output depicting the data spaces for the selected data sets having three mutually perpendicular axes selected from: three index pseudo-dimension axes, or a time axis and two index pseudo-dimension axes.
