public class PlotApplet
extends Applet
implements Runnable
Create an Applet that can plot data from a URL. The URL can be specified using either the dataurl or pxgraphargs applet parameter.

The dataurl parameter contains a single URL that refers to the data to be plotted.

The pxgraphargs parameter contains a list of commmand line style arguments, ending in one or more URLs. See the Pxgraph documentation for the format of these arguments.
