Overlay displaying a LIFT chart. More...
Inheritance diagram for GlLiftChartOverlay:Overlay displaying a LIFT chart.
A LIFT chart consists of a frame representing the whole dataset, and of a set of bars inside this frame, each representing an object (typically, annotations). The top of the frame corresponds to the farthest point of the dataset (as seen from the view that contains this overlay), while the bottom corresponds to the closest. The ends of each bar correspond to the closest and farthest points of the corresponding objects, relative to the frame. Additionally, a horizontal line marks the current slice shown in the view, also relative to the frame. The number next to this line is the frame number as computed by GlSlice::currentSlice. See LiftChartOverlayController for a usage example (with InteractiveLiftChartOverlay).
