In this section we are providing you an example to create a
Polar Chart. Description of Program For creating a Polar Chart
we use the object of XYDataset. Before creating the object of
XYDataset we have to create the objects of XYSeries for
representing the data. We add the data in this series by add()
method. And then we add this series to XYSeriesCollection by
addSeries() method. XYSeriesCollection object represent the
collection of XYSeries objects, which is used as a dataset.
Description of code Firstly we have to create the object of
XYSeries that is used to represent the data items. XYSeries
s1=new XYSeries("a"); And then we add the data in the series by
add() method. After creating the data series we have to create
the object of XYSeriesCollection object that is used to
represent the collection of XYSeries objects, which is used as a
dataset. JFreeChart chart = ChartFactory.createPolarChart("Polar
Chart", dataset, true, true, false); After added the data in
dataset we create the Polar Chart by invoking
