In general with AJAX this isn't possible... there's no way at present to insert binary data, be it an image, PDF, whatever, into the page, and have the browser render it.
What you would have to do is return HTML instead, which includes an <img> tag pointing to the image on the server, which in this case would be your chart, written out somewhere with some ID. For instance, you might write it to a database, using some unique identifier for the user as a key, and then your <img> tag points to an Action, with the ID as a query string, that retrieves the image from the database based on the ID. So it would go something like: User clicks generate chart button --> Server generates chart, writes to DB ---> Return HTML like <img src="getChart.action?id=1234"/> --> HTML inserted into page, browser requests getChart.action to get image, which is an Action, not an image --> Action retrieves image from DB and returns it --> Chart displayed Frank -- Frank W.
