The Save as Image feature works great.

I need to invoke the image creation in a nother way (it should be eliminated from the user)

Can I do this on the server side?

Can I set the target pathame for the image?

thanks alot

You can tweak your image saving code to save image to a server side folder with out user inteference. But, the chart needs to be rendered once at client side. Once that is done you can use JavaScript FC_Rendered() function to call the saveAsImage() function to send data to server side image saving script where you can save the chart to a file in the server's directory. For this you would need to modify the image saving code not to flush the image create to the resposne stream. Rather save the image.

In php you would need to comment some line and add the destination filename :

// JPEG Header
//header('Content-type:image/jpeg');
// Force download box if not IE
//header('Content-Disposition: attachment; filename="FusionCharts.jpg"');

// JPEG Output with 100 quality
imagejpeg($chart, "ThePathToImage.jpeg", 100);

In JSP it would be :

//response.setContentType("image/jpeg");
//response.addHeader("Content-Disposition", "attachment; filename=\"FusionCharts.jpg\"");
//OutputStream os = response.getOutputStream();
ImageIO.write(chart, "jpeg", new File("PathToSave.jpg")
//os.close();

This way you can modify your ASP.NET code and other codes too.

According to documentation I can add the following to a jsp file:

<SCRIPT LANGUAGE="JavaScript">
      function saveChart(){
         //Get chart from its ID
         var chartToPrint = getChartFromId("chart1Id");
         chartToPrint.saveAsImage();
      }
      </SCRIPT>
.. and it should be enough,

but it doesnt, it stopps at saveAsImage()

Should I add the FC_Rendered()? where?

If I dont want to mess with the jpg location, can I leave the content of FusionChartsSave.jsp as is?

upgrading from ver 2.3 to ver3 should i change FusionCharts.js?

Thanks for your help

I have done all the followings, still,

savaAsImage() doesnt work (I have put alerts before and after).

Can you think of a reason why this function doesnt work?

Thanks

I'm using an xml (build in advanced) to render the FC

myChart.setDataURL(xmlURL);
myChart.render(xmlURL);

maybe this is the reasong the saveAsImage() doent work?

        function FC_Rendered(DOMId) {

            alert(DOMId);

            //getChartFromId(DOMId).saveAsImage();

        }

        var chart = new FusionCharts("Charts/MSBar3D.swf", "chartid", "400", "300", "0", "1");

        chart.setDataURL("Data/chart.xml");

        chart.render("chartdiv");

It works great but now after loading the chart, I see this progress bar and after the image is automaticaly saved I get a blank page instead of the chart.

Can I eliminate this progress bar?

Why do I get a blank page?

Thanks guys again
