Hi,
I have bound a powerchart to some XML and it displays the chart fine. What I now want to do is to retrieve the current XML data back from the chart but I cannot seem to get this working. I have viewed the online demo at http://www.fusioncharts.com/Demos/ScatterReturn/Default.html and that is what I want to achieve, but when I download the source it doesn't work.
I am programming this in ASP.net 2.0 and C# using masterpages and here is my code:
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<script language="JavaScript" src="<%=Request.ApplicationPath %>/Javascript/FusionCharts.js"></script>
<script language="JavaScript">
/**
* readXMLFromChart() method is called when the user pressed the
* button to return XML data
*/
function test()
{
//Get a reference to our chart
var ourChart = getChartFromId("SelectChart");
//Get the data from chart
var xmlRtn = ourChart.getXMLData();
//Show it to user in alert box.
alert(xmlRtn);
}
</script>
<table width='98%' border ='0' cellspacing='0' cellpadding='3' align='center'>
<tr>
<td valign='top' class ='text' align='center'>
<div id="chartdiv" align="center">
FusionCharts.
</div>
<script type="text/javascript">
var chart = new FusionCharts("DragNode.swf", "SelectChart", "550", "400", "0", "1");
chart.setDataXML("<%=XmlFC %>");
chart.render("chartdiv");
</script>
</td>
</tr>
<tr>
<td>
<input id="Button1" type="button" value="button" onclick="test();" />
</td>
</tr>
</table>
</asp:Content>
Any suggestions??
