Examples of ChartRenderingInfo

com.positive.charting.ChartRenderingInfo
A structure for storing rendering information from one call to the JFreeChart.draw() method.
An instance of the {@link JFreeChart} class can draw itself within anarbitrary rectangle on any Graphics2D. It is assumed that client code will sometimes render the same chart in more than one view, so the {@link JFreeChart} instance does not retain any information about itsrendered dimensions. This information can be useful sometimes, so you have the option to collect the information at each call to JFreeChart.draw(), by passing an instance of this ChartRenderingInfo class.
