Hi,
I'm experiencing the same issue with caching XMLs. I've tried the above menitioned solutions(adding noCache to both the .swf and .xml URLs) but they don't work for me. The only difference I find is that I don't call an actual xml file as such, instead i call a .aspx file that automattically generates XML output. Se below for the code I use.
<script language="JavaScript" src="../js/FusionCharts.js"></script>
<div id="chartdiv" align="center">The chart will appear within this DIV. This text will be replaced by the chart.</div>
<script type="text/javascript">
var myChart = new FusionCharts("FusionChartsFree/Charts/FCF_Line.swf?noCache=1", "myChartId", "400", "300");
myChart.setDataURL("XMLData/myStepsLineGraphXML.aspx?noCache=1");
myChart.render("chartdiv");
</script>
I have also enabled HTML no cache using
<meta http-equiv="Cache-Control" content="no-cache" />
, that didn't help either.
Any help would be appreciated.
