How To Checks Whether A Fusioncharts Flash Is Unload

[Damon]

Dears,

 

I have gone through the API Reference, but not found any properties or functions that i can use to checks whether a FusionCharts flash is unload.

 

Could any body give me a hand? Thanks very much.

Hi,

 

You can check with the dispose event.

Hi,

 

Since I do not know what chart type you are rendering, I am putting up a generic example. This example does the following:

 

1. 
    
   
2. Renders a Column 3D chart.
   
3. When it is disposed clicking "Unload Chart" button the 'disposed' event is listened.
   
4. An alert is shown through the event listener function stating that the chart is unloaded.
   

 

 

<div id="chartContainer">FusionCharts will load here!</div>

<script type="text/javascript"><!--

   var myChart = new FusionCharts( ".../Charts/Column3D.swf", "myChartId", "400", "300", "0");
   myChart.setXMLData('<chart caption="Weekly Sales Summary" xAxisName="Week" yAxisName="Sales" numberPrefix="$"><set label="Week 1" value="14400" /><set label="Week 2" value="19600" /><set label="Week 3" value="24000" /><set label="Week 4" value="15700" /></chart>');
   myChart.render("chartContainer");

   FusionCharts.addEventListener ( "Disposed", function (identifier, parameter) {
       alert("Your chart with ID: " + identifier.sender.id + " has been unloaded.");
   });

</script>

<input  onClick=" myChart.dispose();" value="Unload Chart" type="button"/>
