Is there an onLoad event to know when the graph finished rendering?

[kappuz]

I want to know if something like this exists (for attaching actions when the graph finished rendering):

 

 

 

 

 

theGraph.onFinishedRender = function afterRender() {

 

 

 

//Make actions when the graph has been rendered

 

 

 

}

 

 

 

theGraph.render();

 

 

 

 

 

Thanks!

Do you need this event for JavaScript or Flash?

[kappuz]

For Flash....

[Pallav]

I'm afraid we do not have such an event in Flash.

[kappuz]

Then it is impossible to know when the graph finished rendering?.... is there any property I can check to know if it has finished rendering?....

 

 

 

 

 

I hope there is something.....

Pallav:

 

 

 

What is the last function called when a graph is rendered?, I think i can dispatch an event from there.

 

 

 

Thanks!

For each chart, it differs.

render() is the consolidated chart method that calls all the chart methods in a sequence at the given time interval (based on animation pattern). We use setInterval and clearInterval to call these methods at the required time interval. So, even the event would need to be called as a part of the last function in the sequence of that chart.

I too need to know how to determine when a chart has finished rendering.

 

 

 

I need this because I have a flash movie where a user can choose a chart-type to show a particular set of data. At present, switching between chart types too quickly causes conficts and weird draw problems even though I am removing the old chart movieclip or using the destroy method and then re-creating a new chart.

 

 

 

If I could test when the render has finished I could disable switching chart type until the chart is finished rendering.

 

 

 

 

 

 

 

ade.

I've added this as a feature extension for future versions.

I have a solution to your problem. :cool:

 

 

 

I started by trying to predict when the chart would be rendered with the undocumented flash function setTimeout, but realized that this would lead to many problems down the road. Unknowns like HTTP XML loading, server load and response times, client CPU, and other variables are out of your control.

 

 

 

I would recommend using setInterval approach to check to see if a known movie clip has been rendered.

 

 

 

This is how I accomplished running something after render was complete:

 

 

 

// Due to the fact that Flash has a horrible XPath implementation,

// I am using X Factor Studio's very nice XPath class.  Highly recommended.

// http://xfactorstudio.com



function setHandlers(){

// set handlers for Anchor points

var datasets:Array = XPath.selectNodes(dataSet.firstChild, '/chart/dataset');

for(var i:Number = 1; i <= datasets.length; i++){

	var set_arr:Array = XPath.selectNodes(datasets[i - 1], 'set');

	for(var j:Number = 1; j <= set_arr.length; j++){

		trace("_level0.ChartHolder_0.Chart.Anchor_"+i+"_"+j);

		_level0.ChartHolder_0.Chart["Anchor_"+i+"_"+j].onRollOver = function(){

			trace("You just rolled over me: "+this._name);

		}

	}

}

}



function isRendered(){

// Goal: test if XML is loaded.

//         test if last Anchor point has been added to the Chart

trace("isRendered called");

if(dataSet.loaded){

	// get the array of datasets from our XML

	var sets:Array = XPath.selectNodes(dataSet.firstChild, '/chart/dataset');

	// get the last dataset's set nodes

	var lastSet:Array = XPath.selectNodes(dataSet.firstChild, '/chart/dataset[last()]/set');

	// I will test to see if the last expected Anchor has been drawn

	// example _level0.ChartHolder_0.Chart.Anchor_1_12

	if(_level0.ChartHolder_0.Chart["Anchor_"+(sets.length)+"_"+(lastSet.length)] != undefined){

		clearInterval(my_interval); // clear the interval isRendered test

		setHandlers();

	}

}

}



var my_interval:Number = setInterval(isRendered, 250); // test isRendered every 1/4 second

Hi, I think this is very useful, but can I know in detail how to use this? like where should I place those code?
