In the below method how do I get the return stuff from JFreeChart to be put
into a NSData which is bound to the <data> binding of a WOImage, which is the
way I've see to use for the Line Chart I'm creating. It seems that JFreeChart
uses .png by default, which is good n'est-ce pas?
public NSData lineChartJFree() {
XYSeriesCollection dataSet = createDataset();
JFreeChart lineChart = createChart( dataSet );
BufferedImage bufFromJFree = lineChart.createBufferedImage( 800, 500 );
Raster rast = bufFromJFree.getData();
return new NSData( rast.??? );
}
