I have renamed the file scatter02.html into scatter02.asp

Message [No canvas support] appeared

Is it possible to use scatter graph with ASP script?

Please advice.

Hi.
Are you using MSIE? This is usually as a result of not having a DOCTYPE at the top of you file. Add this:

<!DOCTYPE html >

on the very first line of your file.

Hi,

I use MSIE 8

See content of scatter02.asp below (no problems with scatter02.html, same script, only different file type)


<!DOCTYPE html >
<html>
<head>
     <link rel="stylesheet" href="demos.css" type="text/css" media="screen" />
     <script src="RGraph.common.core.js" ></script>
     <script src="RGraph.scatter.js" ></script>
     <!--[if lt IE 9]><script src="excanvas.js"></script><![endif]-->
</head>
<body>
     <canvas id="cvs" width="630" height="415">[No canvas support]</canvas>
     <script>
         window.onload = function ()
         {
             // Create and configure the Scatter chart
             var scatter = new RGraph.Scatter('cvs', [
                                                  [200,785, 'blue'],
                                                  [165,225, 'red'],
                                                  [2655,1795, 'red'],
                                                  [2695,190, 'red'],
                                                  [1895,915, 'red'],
                                                  [2630,1700, 'red'],
                                                  [215,1020, 'red'],
                                                  [2465,1330, 'red'],
                                                  [0,0, 'blue'],
                                                  [2999,1999, 'yellow'],
                                                  [1500,1000, 'purple']
                                                 ]);
             scatter.Set('chart.xmax', 3030);
             scatter.Set('chart.ymax', 2015);
             bubble = new RGraph.Scatter.Bubble(scatter, 0, // Minimum
                                                         100, // Maximum
                                                         15, // Max width
                                                         [50,50,50,50,50,50,50,50,50,50,50] // Bubble data
                                                        );
  bubble.Draw();
         }
     </script>
</body>
</html>

Hi,

If all you're changing is the file extension then it may be a server configuration issue.
