I have been trying to figure out a way to create a LineChart that contains numerous LineSeries based off data in an ArrayCollection.
To be more specific, let's say that we have an ArrayCollection about the remote object which will be user for get data , as such:
a KC CLASS which attribute include wordLocal,wordsCount,words
var arr:ArrayCollection = event.result as ArrayCollection;
var kc:KC= new KC();
for(var i:int=0;i<arr.length;i++){
kc=arr.getItemAt(i) as KC;
var word:String = String(kc.words);
var row:int = kc.wordLocal as int;
var wc:int= kc.wordsCount as int;
datasource.addItem({rows:row,word:wc});
}
I want to create a LineChart that contains : the words rows localtion and wc times appeat in total ,such as word "a", The line for "a" on the single line,which xField is rows,yField is wc .
I was thinking that I would probably have to create the LineSeries dynamically
Any suggestions would be helpful. Thanks

I am in the need of multiple staged WebViews for holding multiple loaded websites at the same time.
I was hoping to manage this by making an array of webviews object, so i could call them later as view[i].
var view:Array=[webview0, webview1, webview2];
for each (var v in view){
var v:StageWebView = new StageWebView();
This gives error: 1086: Syntax error: expecting semicolon before left bracket.
Does someone know how to make an array like that?
You're doing something really weird there in terms of syntax. If you just want an Array of freshly created instances, it goes like that:
// Initialize the array.
var Views:Array = new Array;
// This loop counts 0,1,2.
for (var i:int = 0; i < 3; i++)
{
// Create a new instance.
// Yes, you can omit () with new operator if there are no arguments.
var aView:StageWebView = new StageWebView;
// Assign the new element to your array.
Views[i] = aView;
}
Or, if you need only 3 then you don't need to go algorithmic.
var Views:Array = [new StageWebView, new StageWebView, new StageWebView];
Not on topic but related:
Here is an example of one HTML page hold multiple StageWebViews

Im really stuck. I have 5 MC´s that are being spliced from one array at a certain time. In that same function I want to push another movieclips into another array. The two arrays holds mc's that represent right or wrong answers. So when one question is being given a correct answer that questions visualisation alters.
This function holds a incrementing variable as I do want the mc's to be pushed by the user and one at the time. The thing is I cant seem to refer them properly.
I´ve tried
pQuestSum = this[pQuest + pQuestNumber];
and
pQuestSum = this[pQuest] + pQuestNumber;
and pretty much everything I´ve imagined would work...but the problem is I havent tried
the right thing.
when I trace pQuestSum (which would be the reference) I get an error saying thats its not a number.
this is one of 5 mc's named from 1-5:
var passedquest1:PassedQuest = new PassedQuest();
this is the vars that i try to to build a reference of
var pQuest = "passedquest";
var pQuestNumber = 1;
var pQuestSum;
var questCorrArray:Array = [];
if(event.target.hitTestObject(questArray[ix])){
removeChild(questArray[ix]);
questArray.splice(ix,1);
pQuestNumber ++;
pQuestSum = this[pQuest] + pQuestNumber;
trace("pQuestSum"); // NaN
questCorrArray.push(pQuestSum);
//trace(questArray.length);
pointsIncreased = false;
questPoints = 0;
}
How do I refer an existing movieclip when the reference consists of both a string and a number? Hope I made myself somewhat clear:)
If you had an instance of an object on your timeline called "passedquest1" (as an example), then you could access it this way:
var myObj = this["passedquest" + 1];
Or,
var pQuest = "passedquest";
var pQuestNumber = 1;
var myObj = this[pQuest+ pQuestNumber.toString()];
When you do this: pQuestSum = this[pQuest] + pQuestNumber;, you are trying add the number to an object (this[pQuest]), unless you have number/int var called "passedquest", this will result in NaN.
Introduction:
I have an AdvancedDataGrid displaying hierarchical data illustrated by the image below:
The branch nodes "Prosjekt" and "Tiltak" display the sum of the leaf nodes below.
Problem: I want the root node "Tavle" to display the total sum of the branch nodes below. When i attempted to do this by adding the same SummaryRow the sum of the root node was not calculcated correctly(Every node's sum was calculated twice).
dg_Teknikktavles = new AutoSizingAdvancedDataGrid();
dg_Teknikktavles.sortExpertMode="true";
dg_Teknikktavles.headerHeight = 50;
dg_Teknikktavles.variableRowHeight = true;
dg_Teknikktavles.addEventListener(ListEvent.ITEM_CLICK,dg_TeknikktavlesItemClicked);
dg_Teknikktavles.editable="false";
dg_Teknikktavles.percentWidth=100;
dg_Teknikktavles.minColumnWidth =0.8;
dg_Teknikktavles.height = 1000;
var sumFieldArray:Array = new Array(context.brukerList.length);
for(var i:int = 0; i < context.brukerList.length; i++)
{
var sumField:SummaryField2 = new SummaryField2();
sumField.dataField = Ressurstavle.ressursKey + i;
sumField.summaryOperation = "SUM";
sumFieldArray[i] = sumField;
}
var summaryRow:SummaryRow = new SummaryRow();
summaryRow.summaryPlacement = "group";
summaryRow.fields = sumFieldArray;
var summaryRow2:SummaryRow = new SummaryRow();
summaryRow2.summaryPlacement = "group";
summaryRow2.fields = sumFieldArray;
var groupField1:GroupingField = new GroupingField();
groupField1.name = "tavle";
//groupField1.summaries = [summaryRow2];
var groupField2:GroupingField = new GroupingField();
groupField2.name = "kategori";
groupField2.summaries = [summaryRow];
var group:Grouping = new Grouping();
group.fields = [groupField1, groupField2];
var groupCol:GroupingCollection2 = new GroupingCollection2();
groupCol.source = ressursTavle;
groupCol.grouping = group;
groupCol.refresh();
Main Question: How do i get my AdvancedDataGrid's (dg_Teknikktavles) root node "Tavle" to correctly display the sum of the two branch nodes below?
Side Question: How do i add a red color to the numbers of the root node's summary row that exceed 5? E.g the column displaying 8 will exceed 5 in the root node's summary row, and should therefore be marked red
Thanks in advance!
This is a general answer, without code examples, but I had to do the same just couple of days ago, so my memory is still fresh :) Here's what I did:
Created a class A to represent an item renderer data, extended it from Proxy (I had field names defined at run time), and let it contain a collection of values as it's data member. Once accessed through flash_proxy::getPropery(fieldName) it would find a corresponding value in the data member containing the values and return it. Special note: implement IUID, just do it, it'll save you couple of days of frustration.
Extended A in B, added a children property containing ArrayCollection of A (don't try to experiment with other collection types, unless you want to find yourself examining tons of framework code, trust me, it's ugly and is impossible to identify as interesting). Let B override flash_proxy::getPropery - depending of your compiler this may, or may not be possible, if not possible - call some function from A.flash_proxy::getPropery() that you can override in B. Let this function query every instance of A, which is a child of B, asking the same thing, as DataGrid itself would, when building item renderers - this way you would get the total.
When creating a data provider. Create an ArrayCollection of B (again, don't try to experiment with other collections--unless you are ready for lots of frustration). Create Hierarchical data that uses this array collection as a source.
Colors - that's what you use item renderers for, just look up any tutorial on using item renderers, that must be pretty basic.
In case someone else has the same problem:
The initial problem that everything was summed twice, was the result of using the same Array of SummaryField2 (sumFieldArray in the code) for both grouping fields(GropingField2 tavle and kategori)
The Solution to the main question: was to create a new array of summaryfields for the root node(in my intial for loop):
//Summary fields for root node
var sumFieldRoot:SummaryField2 = new SummaryField2();
sumFieldRoot.dataField = Ressurstavle.ressursKey + i;
sumFieldRoot.summaryOperation = "SUM";
sumFieldArrayRoot[i] = sumFieldRoot;
Answer to the side question:
This was pretty much as easy as pointed out by wvxyw. Code for this solution below:
private function summary_styleFunction(data:Object, col:AdvancedDataGridColumn):Object
{
var output:Object;
var field:String = col.dataField;
if ( data.children != null )
{
if(data[field] >5){
output = {color:0xFF0000, fontWeight:"bold"}
}
else {
output = {color:0x006633, fontWeight:"bold"}
}
//output = {color:0x081EA6, fontWeight:"bold", fontSize:14}
}
return output;
}
I am using Vectors in Flash 10 for the first time, and I want to create it in the same way I used to do with Arrays, e.g:
var urlList : Array = [url1, url2, url3];
I have tried various different methods but none seem to work, and I have settled on the following as a solution:
var urlList : Vector.<String> = new Vector.<String>();
urlList.push(url1, url2, url3);
Is this even possible?
When it doubt, check the AS3 docs. :)
var urlList : Vector.<String> = new <String>["str1", "str2", "str3"];
trace(urlList);
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Vector.html#Vector()
Direct quote of the line I adapted this from in the documentation:
To create a pre-populated Vector instance, use the following syntax instead of using the parameters specified below:
// var v:Vector.<T> = new <T>[E0, ..., En-1 ,];
// For example:
var v:Vector.<int> = new <int>[0,1,2,];
You coerce an array to a Vector:
var urlList:Vector.<String> = Vector.<String>([url1, url2, url3]);
so.... eval() out of the question, any idea to do this? I also don't know how to use "this" expression or set() in actionscript 3 ( i seem couldn't find any complete reference on it ), just say through php file a multiple variable (test1, test2, test3,...) sent by "echo", how the flash aplication recieved it? I'm trying not to use xml on mysql to php to flash aplication. Simply how to change a string to a variable ?
example
(in as3-actions frame panel)
function datagridfill(event:MouseEvent):void{
var varfill:URLVariables = new URLVariables();
varfill.tell = "do it";
var filler:URLRequest = new URLRequest();
filler.url = "http://127.0.0.1/flashdbas3/sendin.php";
filler.data = varfill;
var filling:URLLoader = new URLLoader();
filling.dataFormat = URLLoaderDataFormat.VARIABLES;
filling.load(filler);
filling.addEventListener(Event.COMPLETE, datain);
function datain(evt:Event){
var arraygrid:Array = new Array();
testing.text = evt.target.Name2 // worked
// just say i = 1
i=1;
arraygrid.push({Name:this["evt.target.Name"+i],
Test:this.["evt.target.Test"+i]}); // error
//or
arraygrid.push({Name:this["Name"+i],
Test:this.["Test"+i]}); // error too
// eval() noexistent, set() didn't worked on actions frame panel
//?????
}
};
I hope it's very clear.
You could use this[varName] if I understand your question right.
So if varName is a variable containing a string which should be a variables name, you could set and read that variable like this:
this[varName] = "someValue";
trace(this[varName]);
Update:
In your example, you could try: evt.target["Test"+i] instead of Test:this.["evt.target.Test"+i]
If you have a set of strings that you'd like to associate with values, the standard AS3 approach is to use an object as a hash table:
var o = {}
o["test1"] = 7
o["test2"] = "fish"
print(o["test1"])
