Constructor Detail

PlotApplet

public PlotApplet()

Method Detail

getAppletInfo

public java.lang.String getAppletInfo()

Return a string describing this applet.

Returns:

A string describing the applet.

getParameterInfo

public java.lang.String[][] getParameterInfo()

Return information about parameters.

Returns:

A array of arrays giving parameter names, the type, and the default value or description.

init

public void init()

Initialize the applet. Read the applet parameters. Subclasses that extend this method and call Swing UI methods should do so in the Swing Event thread by calling SwingUtilities.invokeAndWait(). Note that some Plot methods will automatically run in the Swing Event thread, some will not. For details about SwingUtilities.invokeAndWait(), see The Sun Applet Tutorial

newPlot

public PlotBox newPlot()

Create a new Plot object for the applet. Derived classes can redefine this method to return a different type of plot object.

Returns:

A new instance of PlotBox.

plot

public PlotBox plot()

Return the plot object to operate on.

Returns:

The plot object associated with this applet.

setPlot

public void setPlot(PlotBox plot)

Set the plot object to operate on.

Parameters:

plot - The plot object to associate with this applet.

_read

protected void _read(java.io.InputStream in)
              throws java.io.IOException

Read the specified stream. Derived classes may override this to support other file formats.

Parameters:

in - The input stream.

Throws:

java.io.IOException - If the stream cannot be read.

_setPlotSize

protected void _setPlotSize(int appletWidth,
                            int appletHeight)

Given the size of the applet, set the size of the plot. Derived classes may override this to allow room for other widgets below the plot.

Parameters:

appletWidth - The width of the applet.

appletHeight - The height of the applet.
