Use the iframe onload method to call another javascript function that will call a PDF generation routine. The process is as follows:<br><br>1. render multiple iframes with charts<br>2. add a button that when clicked calls the saveAsImage function on all iframes<br>3a. the saveAsImage passes the control to a http handler that creates the image and adds it to the cache<br>3b. the last step of the handler writes out a javascript history.go(-1)<br>4. step 3a/3b above is repeated for all iframes on the page<br>5. add an onload method on the last iframe which will react to the onload event when the history.go(-1) is called<br>6. this onload method will pass the control to a render PDF javascript function that will invoke a separate http handler that will read the images from cache and generate a pdf<br><br>if someone has a better method, please let me know.Tue, 29 Apr 2008 22:15:12 GMTexwhyzhttp://www.fusioncharts.com/forum/Topic5992-40-1.aspxIs there a way to track the saveAsImage completion? I have several charts on a page, I have embedded these in an iframe and then I want to track when the saveAsImage completes. And when that happens I would like to retrieve the images from the cache and generate a PDF. Currently I am saving the images to Cache successfully, but would like to know when to invoke the PDF generation routine, without waiting for some arbitrary time. I cannot embed this logic inside imageSaveURL target since I am dealing with multiple charts. It would be really nice if in the next version we can have an elegant way of handling multiple charts without resorting to iframes.<br><br>Thanks!Mon, 28 Apr 2008 23:41:34 GMTexwhyz
