Hi there,<br/><br/>I successfully created a chart. Because I want to use it dynamic, I use querystring and load this form in an iFrame. Everything (including tooltips) worked fine.<br/><br/>But I'm not really a fan of iframes. So I decided to return the graph as an image. Now I can use this char in an &lt;IMG&gt; tag instead of an &lt;IFRAME&gt; tag.<br/><br/>It works and I am able to load the chart in an image tag, but the tooltips are lost now. Is there any way to prevent this, or should I switch back to the first approach?© 2009 Microsoft Corporation.

That is the approach I use to display the chart in an &lt;img&gt; tag.
