Re: how to dynamically add multiple LineSeries to a chart?

[modjklist]

Hi Jonathan, 

I implemented your architecture below (using s.dataProvider instead of 
s.dataField) and adding some code before and after it as follows:

// from: http://tjoadesign.nl/blog/?p=334
for each ( var lineSeries:LineSeries in chart.series )  
    lineSeries.dataFunction = null ; // note: this appears to null here by 
default anyway

-- start Jonathan's code---

var i:int = -1; 
var n:int = yourData.length; 
var genLineSeries:Array = []; 
while(++i<n) { 
var s:LineSeries = new LineSeries(); 
   //add properties as necessary to series 
   s.dataProvider = yourData[i].dataField; 
   genLineSeries.push(s); 
} 
chart.series = genLineSeries; 

-- end Jonathan's code---

chart.invalidateDisplayList();


Now there's a memory leak seen using Flash Builder profiler each time I toggle 
between two different plots. The memory occupied by LineSeries increases every 
time a plot (new, or old) is generated, forever.  

Is there something that needs to be reset or initialized somewhere?

It's actually much easier than you are even doing it, pseudo code to follow: 

//loop your data describing the series that will be created 
var i:int = -1; 
var n:int = yourData.length; 
var genLineSeries:Array = []; 
while(++i<n) 
{ 
var s:LineSeries = new LineSeries(); 
//add properties as necessary to series 
//based on your data 
s.dataField = yourData[i].dataField; 
genLineSeries.push(s); 
} 
//assuming your chart 
lineChart.series = genLineSeries; 

//done
