I want to load dynamic data for the chart inside the update panel. I used the InFunction to call the js to render the chart using Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler)

But after update panel finish update the redraw the chart with old data when I init it in the pageload. is there any way to refresh the chart with new data?
