Handling massive data with JavaScript chart library

Question

I am interested in any experience using JS charting packages handling massive amounts of data (for example tens of thousands of data points).

Any performance issues? Browser memory consumptions? Any other issues? Would anyone recommend a particular JavaScript charting library for that?

Thanks

Answer 1

I have used google maps to display polylines; I've been facing huge performance issues when the polylines had more than a thousand points.

Answer 2

Javascript is processed linearly, so the more data loaded, the longer it takes. I would suggest a load on demand type of charting, showing only a part of the data at any one time.

Otherwise i would suggest moving to Flash / Silverlight (if you are developing in .NET)

Edit

Visifire for Silverlight. it is open source and can be found at http://visifire.com/.

Also, MS just released the MS Chart Controls (http://code.msdn.microsoft.com/mschart), which need .NET FrameWork 3.5 SP1, these can be used natively in WinForms / ASP.NET (server rendered, using ASP.NET AJAX load on demand would be a easy).

FusionCharts is free for Flash: http://www.fusioncharts.com/free/
