What is Animated Brushing?
Typical applications of animated brushing are in exploratory data analysis using matrix plots (see the previous topic), where instead of brushing consecutive ranges of a variable (to explore the influence of various sections of its distribution), you can invoke an automatic movement of the brush (Box, Lasso, Slice X, Slice Y, Slice Z, or Cube) and watch the “results.” Specifically, a brushing region is defined in one subgraph in the matrix and is automatically moved across the subgraph (horizontally, vertically, or both). As the brushing region passes over groups of points in the subplot, corresponding points in all other plots are highlighted. For example, in the illustration below, the rectangular region can be advanced automatically across groups of points in the Income, and the corresponding points will be highlighted in plots of the other three variables. The speed and direction of the movement can be interactively controlled in the Animation dialog. The Animate button is availabl
