We are using the setDataXML method to present the XML for several different charts that we have embedded on a community page for our users. When the users first log onto the community page, the charts are usually in dissarray, i.e. sometimes producing the same chart over and over again or displaying old data. In order to recover from this, the users must refresh their browser cache. So we looked at this problem in Fiddler and confirmed that the chart info in the browser cache is not being refreshed from the server at startup. We found that this only happens in IE and not in Firefox. Apparently, there are ways of getting around this using the setDataUrl method but have not found any solutions for this using the setDataXML method.
Does anyone know how to get around this problem using the setDataXML method? We are using FusionCharts v3.1. Any help that you can provide would be appreciated. Thanks.
Here is a snippet of the method that is being used:
<td align="center">
<div id="Chart1Div" align="center">This text is replaced by the chart</div>
<script type="text/javascript">
var Chart1 = new FusionCharts("MSLine.swf", "Chart1Id", "600", "400", "0", "1");
Chart1.setDataXML("{xml_result1}");
Chart1.setTransparent(true);
Chart1.render("Chart1Div");
</script>
</td>
