The Parameter Server allows Chart Viewer to listen to requests from a specified port using TCP/IP and update the data dynamically. The syntax is:

<applet code = "quadbase.chartviewer.Viewer.class" width=640 height=480>
	<PARAM name="ParameterServer" value="machine:portno"> 
</applet> 

For security reasons, the machine is usually the same as the web server machine. Therefore, you can leave machine empty (i.e. value=":portno").
