you can easily use JFreeChart for making very nice
and complex charts with processing like this:
Code:
PImage chartImage;
void setup(){
size(500, 300);
// create a dataset the chart is generated from
DefaultPieDataset dataset = new DefaultPieDataset();
dataset.setValue("Processing", new Integer(75));
dataset.setValue("Other", new Integer(25));
// create the chart from dataset
JFreeChart chart = ChartFactory.createPieChart("A Pie Chart", dataset, true, false, false);
// create image from chart
chartImage = new PImage(chart.createBufferedImage(500,300));
}
void draw(){
// display chart image on screen
image(chartImage, 0, 0);
}
note: import jfreechart-1.0.0.jar & jcommon-1.0.0.jar
to your sketch.
but if you're going to use this in applets, you should
take into account the size of the jFreeChart library.
