public class PlotApplet

extends java.applet.Applet

implements java.lang.Runnable

Applet showing a static plot in a GraphicsPlotCanvas. The plot (data as well as layout) is defined by applet parameters. Depending on the applet parameters the data may be loaded from a separated file. This allows to separate model (data) from view (plot). Before the plot is shown a waiting message is presented.

The applet parameters are organized in a hierarchical way with inheritance as explained in FlatConfigData. The PlotApplet uses the same configiuration parameters as the constructor of GraphicsPlotCanvas. In addition the following parameters are considered:

Key & Default Value	Type	Mandatory	Description
waitingMessage = Please wait, applet data are loading...	String	no	Message present after the applet has be started.
dataProperties	String	if data is absent	File name relative to the applet's document base. It should denote a .properties file with the configuration parameters for the constructor of DataPlot.
data	ConfigParameters	if dataProperties is absent	Configuration parameters for the constructor of DataPlot.
renderer = jcckit.renderer.GraphicsRenderer	String	no	Fully qualified class name of the render which has to be the default renderer or a subclass of the default renderer.
