Dynamic JSON data (or XML)

I'm trying to load dynamic data to JSCharts. To do so, I have an ASP.NET HttpHandler on my server that returns JSON formatted data, I then set the setJSONData method to point to the URL of my HTtpHandler. Will that work with JSCharts? If not how do I handle dynamic data with JSCharts? Seems like it should be able to do so. Thanks!

I did something like this but with XML.

Are you using MVC or ASP.NET webforms?

I just passed a HtmlString to a partial page containing off of my charts and popped that into the js

ex:
myChart.setDataXML("@Model.xmlString", true);

Hope that points you in the right direction.
