Zusammenfassung:An algorithm is provided for optimizing the layout of labels associated with a visual data object such as a chart. The labels are first placed into a chart definition file that defines the labels as a shape. An initial layout of the labels is created and scored. The shapes are then manipulated iteratively until an optimal layout of the labels is obtained that corresponds to the layout having the score closest to an optimal score. The optimal layout is then used in rendering the visual data object on a screen.
