I want to generate graph using the values of the database dynamically . I have developed this code but it's still not working......help us ASAP.The two javascript files that are used as a source are downloadable from www.dynamicdrive.com & write graphs in search tab.


<% mypack.Student s=new Student();
ResultSet rs=s.viewAllB(); %>

<html>
<head>
<title>Graph</title>
<script type="text/javascript" src="C:\Documents and Settings\HP_Owner\Desktop\site2\line.js"></script>
<script type="text/javascript" src="C:\Documents and Settings\HP_Owner\Desktop\site2\wz_jsgraphics.js"></script>
<script type="text/javascript">
function drw()
{
var g = new line_graph();
g.add(rs.getString(2),rs.getString(1));
g.add("12",70);

g.render("canvas_name", "statistics");
}

</script>
</head>
<body>
<input type="button" onclick="drw()" value="Click"/>

<div id="canvas_name" style="margin-top:500;margin-left:500">

What does "not working" mean - does the computer blow up?

It means that after clicking the button graph is not displayed on the screen.

Some questions in no particular order (all of which you'll need to be able to answer in order to figure this out): What's the output you're getting in your browser's console? What's the output you're getting in your servlet container's log file? What is the HTML that's getting generated - is it correct, and as you imagined it would be? Is the function "drw" being called?

I don't see anything that pertains to Applets. Moving to the HTML, CSS and JS forum.
