Manipulate View

11.1 The Big Picture

Figure 11.1 shows the design choices for how to manipulate a view: to change anything about it, to select items or attributes within it, and to navigate to a different viewpoint.

Figure 11.1.

Figure Showing design choices for idioms that change a view.

Design choices for idioms that change a view.

The ways to change a view cover the full set of all other design choices for idioms. A change could be made from one choice to another to change idioms, and any of the parameters for a particular idiom can be changed. Any aspect of visual encoding can be changed, including the ordering, any other choice pertaining to the spatial arrangement, and the use of other ...
