Empty image with DragNode export

Recommended Posts

I use the DragNode chart for representing relations between different objects. The generated image contains only text, the connectors and colors are not present.




For the export I use this code :


function FC_Rendered(objRtn){


var myChart = getChartFromId(objRtn);




myChart.exportChart( {


exportFormat : "JPG",


exportAtClient : 0,


exportFileName : "mychart",


exportAction : "save",


exportHandler : "includes/powercharts/ExportHandlers/PHP/FCExporter.php" });
