A computer graphics display method and system for controlling data visualization in at least one external dimension is provided which allows better querying and navigation of data in external dimension space. A data visualization is displayed in a first display window. A summary window provides summary information on data for the data visualization across one or more external dimensions. First and second controllers are displayed for controlling the variation of the data visualization in respective first and second external dimensions. A user queries the data visualization in the first and second external dimensions by selecting a point in the summary window. A user navigates through the data visualization in the first and second external dimensions by defining a path in the summary window. Grid points are also displayed in the summary window to facilitate data queries and navigation based on actual data points. The first and second controllers can be first and second sliders, such as, slide buttons, dials, or any other type of input. An animation control panel, including tape-drive controls, a path control, and a speed control, controls an animation of the data visualization over a selected navigation path through external dimension space.
