I'm not sure I can yet visualize what you're seeking... type of chart (fever, bar, pie, etc)... type of data source (web service, inline data, form-based, etc)... type of interactions ("zoom in" sounds like some type of drilldown, or maybe it's a timeline expansion, etc). Am I correctly understanding that you have all the serverside data generation and request handling already taken care of, and that you're just looking for some types of clientside charting of this data, in each user's browser? If so, then the richest charting I know of is in Adobe Flex 2... samples can be tested on this page, under the "Charts" category: http://examples.adobe.com/flex2/inproduct/sdk/explorer/explorer.html Or maybe you were looking for a literal "zoom in" timeline slider, like Measuremap...? http://www.measuremap.com/developer/slider/ Or...? jd -- John Dowdell .
