This question was posted in response to the following article: http://help.adobe.com/en_US/ColdFusion/10.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c2 4-7934.html
This uses the renderer from CF9. So chart types and features from the CF10 (zingchart) library don't work, and charts look completely different from those rendered with format="html"
This is good to be reminded of, but it stands to reason: ZingCharts are rendered by the browser, not by the CF engine, so CF can't pre-render those charts, and it doesn't really make sense to try: the only "rendering" CF would be able to do is to write out the code sent to the browser: there's no performance economy to be had there. The "NAME" option should probably be disallowed when using FORMAT="HTML", I think.
