</APPLET>

The configuration parameters are taken from the text file piepropsjs.txt ( click here to view )
and the graph data is read from the text file piedatajs.txt ( click here to view )

If you "right click" and view source of this page you will see that we have the following javascript function within the page which is able to act upon the three tables, "c1", "c2" and "c3".

<SCRIPT LANGUAGE="JavaScript">

var table='c1';
function combo(table) {

if (table=='c1') {
if (document.all.c1.style.visibility=="hidden") {
document.all.c1.style.visibility="visible";
}
else {document.all.c1.style.visibility="hidden";}
}

if (table=='c2') {
if (document.all.c2.style.visibility=="hidden") {
document.all.c2.style.visibility="visible";
}
else {document.all.c2.style.visibility="hidden";}
}

if (table=='c3') {
if (document.all.c3.style.visibility=="hidden") {
document.all.c3.style.visibility="visible";
}
else {document.all.c3.style.visibility="hidden";}
}

}

</script>

In the piedatajs.txt ( click here to view ) file you will see that each of our data elements has the word "javascript" entered in the target field and the javascript function name with the relevant value entered in the URL field.
