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).

ChartPanel

public ChartPanel(JFreeChart chart,
                  boolean properties,

                  boolean zoom,
                  boolean tooltips)
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.
