How To Export Child Chart Using External Button

[ppek]

Hi,

I'm trying to write code which exports a chart to a file. It works with parent chart but doesn't work according to the child chart (I have links in XML file to "go deeper" into the chart details).

 

function testPrint(chartName) {

var chart = getChartFromId(chartName);

if (chart.hasRendered() != true)
{
	alert("Please wait for the chart to finish rendering, before you can invoke exporting");
	return;
}

// call exporting function
chart.exportChart( {exportFormat: "PNG"} );
}

 

 

Being on the deeper level using this code causes 'Unspecified error'.

Please, help.
