    PolarChartPanel is the top level object for using the PolarPlot. Since this class has a JPanel in the inheritance hierarchy, one uses this class to integrate the Polar plot into their application.

    The main modification to ChartPanel is the popup menu. It removes ChartPanel's versions of:

    • Zoom In
    • Zoom Out
    • Auto Range
    and replaces them with versions more appropriate for PolarPlot.
