public class ChartPanel extends JPanel implements ChartChangeListener, ChartProgressListener, ActionListener, MouseListener, MouseMotionListener, OverlayChangeListener, Printable, Serializable
A Swing GUI component for displaying a JFreeChart object.

The panel registers with the chart to receive notification of changes to any component of the chart. The chart is redrawn automatically whenever this notification is received.

    • ChartPanel

      public ChartPanel(JFreeChart chart)
      Constructs a panel that displays the specified chart.
      Parameters:
      chart - the chart.

    • ChartPanel

      public ChartPanel(JFreeChart chart, boolean useBuffer)
      Constructs a panel containing a chart. The useBuffer flag controls whether or not an offscreen BufferedImage is maintained for the chart. If the buffer is used, more memory is consumed, but panel repaints will be a lot quicker in cases where the chart itself hasn't changed (for example, when another frame is moved to reveal the panel). WARNING: If you set the useBuffer flag to false, note that the mouse zooming rectangle will (in that case) be drawn using XOR, and there is a SEVERE performance problem with that on JRE6 on Windows.
      Parameters:
      chart - the chart.
      useBuffer - a flag controlling whether or not an off-screen buffer is used (read the warning above before setting this to false).

    • ChartPanel

      public ChartPanel(JFreeChart chart, boolean properties, boolean save, boolean print, boolean zoom, boolean tooltips)

      properties - a flag indicating whether or not the chart property editor should be available via the popup menu.
      save - a flag indicating whether or not save options should be available via the popup menu.
      print - a flag indicating whether or not the print option should be available via the popup menu.

      properties - a flag indicating whether or not the chart property editor should be available via the popup menu.
      save - a flag indicating whether or not save options should be available via the popup menu.
      print - a flag indicating whether or not the print option should be available via the popup menu.
