Hi,
 I create my chart through the php connector:
  
 
  
$columnChart = new FusionCharts( 
"line",  
"ex1" ,  
"500",  
"235",  
"chart-1",  
"json",  
'{   
  "chart": 
  {   
 "caption":"Trend (all countries)", 
"xAxisName": "",
 
 etc.
  
 How can I activate the export to csv?
  
 I tried to add "showexportdatamenuitem":"1", but it does not work.
  
 Thank you in advance
