public class GraphDiagram

extends Applet

implements GraphListener, Runnable

GraphDiagram()

Constructs a graph which runs in its own thread.

addGraphListener(GraphListener)

Adds a graph listener to the output.

clear()

Clears the graph

data(String, double, double)

Adds a data element

display()

Displays the graph

forwardGraph(GraphEventObject)

Sends graph events to any listeners

get_diag()

Returns the panel associated with this graph

handleGraph(GraphEventObject)

Deals with incoming graph events

init()

Sets up graph diagram display

main(String[])

Constructs an example using the graph, by connecting a GraphEqn object to its input to display sine waves.

removeGraphListener(GraphListener)

Removes a graph listener from the output.

run()

Draws graph
