ABSTRACT:
A zoom control mechanism includes a context display for displaying a representation of a data set, a zoom display for displaying a representation of a zoom interval within the data set, a context indicator that indicates a start point or an end point of a zoom interval within a context display, and a zoom indicator, corresponding to the context indicator, that indicates the start point or end point of the zoom interval within the zoom display. The zoom interval is updated according to user selection and movement of the context indicator and the zoom indicator to a new location within the context display and the zoom display, respectively.
