Space Series : simultaneous display of spatial and temporal data

Space Series is a new focus-plus-context technique for presenting both spatial and temporal data in a single 2D plot. Initially, the display shows an overview of the temporal distribution of the data. Focus is then interactively applied along the X-axis, the Y-axis, or both, expanding the spatial dimension of the data set. When focusing is applied simultaneously along both axes, twodimensional spatial details are shown at their intersection. This visualization technique is illustrated with examples from a simulation of architectural daylighting.
