        public static final boolean DEFAULT_BUFFER_USED
        Default setting for buffer usage. The default has been changed to true from version 1.0.13 onwards, because of a severe performance problem with drawing the zoom rectangle using XOR (which now happens only when the buffer is NOT used).

    • Constructor Detail

      • 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).

        Constructs a JFreeChart panel.
        Parameters:
        chart - the chart.
        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.
        zoom - a flag indicating whether or not zoom options should be added to the popup menu.
        tooltips - a flag indicating whether or not tooltips should be enabled for the chart.

        Specified by:
        mousePressed in interface MouseListener
        Parameters:
        e - The mouse event.
      • mouseReleased

        public void mouseReleased(MouseEvent e)

        Specified by:
        mouseReleased in interface MouseListener
        Parameters:
        e - information about the event.
