setDataURL only works after running the function twice or delaying with an alert

[evanluck]

I'm using JQuery and am running into a problem with the setDataURL function. It works the second time I execute the function but not the first. If I delay the running of the function with an alert, the function will work the first time.

 

 

 

Tried to implement a setTimeout solution but could not get that to work at all.

 

 

 

example can be seen here:

Code excerpt is below:

 

 

 

     //updateChart method is called whenever the user clicks the button to

     //update the chart. Here, we get a reference to the chart and update it's

     //data using setDataURL method.

     function updateChart(service,percent){

        //Get reference to chart object using Dom ID

        var chartObj = getChartFromId("rankgraph");

	 //assemble new data URL from arguments -dc replace with php script DONE

	 var theURL = "services_like_me_all.php"+"?service="+service+"&percent="+percent;

	 //set new URL

	 //alert(theURL);

        chartObj.setDataURL(theURL);



     };



  function findSegmentsbyService() {

  $('#graphbox').show();

  var theService = $('#serviceselectbox').val();

  var thePercent = $('#atleast').val();

  $("#insservice").html(theService);

  $("#inspercent").html(thePercent);

  updateChart(theService,thePercent);

  };

Hi,

 

 

 

The setDataURL function is available only after the chart is rendered.

 

 

 

This can be tracked down by placing FC_Rendered(DOMId) JavaScript function . The chart would call the function once the chart is ready for setDataURL().

 

 

 

Please call setDataURL() only after FC_Rendered() is called.

Thank you for the reply...

 

 

 

Given my function, can you give me an example of how to implement the FC_Rendered(DOMId) function.

 

 

 

I tried and couldn't get it to work
