Stack Zooming for Stock Market Data


Stack Zooming


To support the comparison of time-series data, Javed and Elmqvist (2010) developed a technique called "stack zooming":
"The approach is based on the user interactively building hierarchies of 1D strips stacked on top of each other, where each subsequent stack represents a higher zoom level, and sibling strips represent branches in the visual exploration. Correlation graphics show the relation between stacks and strips of different levels, providing context and distance awareness among the focus points. The zoom hierarchies can also be used as graphical histories and for communicating insights to stakeholders." Such a functionality should be implemented for time and its granularities.
