Abstract
Rendering electronic chart objects is provided. A set of chart elements having a common set of properties is identified. Formatting attributes of the chart elements and the data point locations for each chart element are also identified. Path information is generated for the chart elements that includes the formatting attributes and the data point locations. The path information is provided to a rendering engine that renders a chart element. Each chart element in the set is displayed on a display screen. Chart elements having a common set of properties are only rendered once. Alternatively, chart objects are rendered by generating and storing an image of chart objects having a common geometry and common properties and by copying the stored image to each data point location. Dynamic selection of rendering engines based on property and performance criteria may be utilized to enhance rendering performance.
