I am having same issue of Fusion Chart not refreshing.
I am drilling down the pie chart.
As we click the pie, a ajax request goes to server.
On server I am building a xml file with same name as that of earlier one.
var graphPath = "FusionDataXML/PieChart.xml";
var myChart = new FusionCharts("FusionCharts/FCF_Pie2D.swf", "myChartId", "450", "300");
When we manually delete the cache and start drilling down correct values are reflecting only for 2-3 times. But then after old pie chart is displayed again and again.
I checked the xml. The data is changing every time.
Is there any way to solve the issue.
I have tried the code -
// These headers are required to prevent caching in IE
response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT");
// set standard HTTP/1.1 no-cache headers
response.setHeader("Cache-Control","no-store, no-cache, must-revalidate");
// set IE extended HTTP/1.1 no-cache headers
response.addHeader("Cache-Control", "post-check=0, pre-check=0");
// set standard HTTP/1.0 no-cache header
but it is not the solution.
