Description copied from interface: ChartPostProcessor

Processes a generated chart. This method is called by the ChartProducer after a chart instance is generated and before it is rendered (if so). The ChartProducer is responsible for post processing a chart dependant on and only on the provided parameters. This means that the same parameters should result in the same post processings.

Specified by:

processChart in interface ChartPostProcessor

Parameters:

chart - the chart instnce. Concrete class depends on the rendering implementation. Currently a org.jfree.chart.JFreeChart is passed.

args - paramters passed to the postprocessor. These are defined in the JSP
