You may want to consider an approach similar to this: http://blog.tsclausing.com/post/19 I actually use filters and data functions on my axes/series to change the way the data appears, instead of changing out the separate data source. If you contact me off list (amy at magnoliamultimedia dot com), I can send you some code that shows this. But I don't have time to strip it of the client-specific stuff to make it a public example, so I'm not going to post it. HTH; Amy
