I am trying to use AlivePDF to save a chart into a .pdf file. However, when I try to save my chart, it ends up clipping half of the chart in the pdf so it isn't even fully visible.

Flex - Refresh Datagrid With Hierarchical Data?

Dec 3, 2009

how can I refresh the displayed data in a Datagrid when the underlying ArrayCollection changes?

<nmoschitz:dataProvider>
<mx:HierarchicalData source="{arrCol_groupedData}"
childrenField="accounts"/>
</nmoschitz:dataProvider>

Calling a simple refresh (like with a simple arraycollection as a dataprovider, or with a refresh on the Grouping Collection) does not work. Also re-assigning the arrayCollection to the Hierarchical Data and then assigning this one again to the Datagrid does not work (even with calling invalidateProperties() or validateNow()).

Flex :: Sort AdvancedDataGrid With Hierarchical Data?

Mar 29, 2011

I have an AdvancedDataGrid with a HierarchicalCollectionView as its dataProvider. When I view the grid with the dataset I'm working with, and click the header of the column I wish to sort on, everything works perfectly. It sorts it hierarchically exactly how I would expect it to.What I want to do now is have the grid already be sorted when it is shown to the user. Is there a way to do this programatically? I can't for the life of me figure out how to do this, and clearly it's possible since the AdvancedDataGrid has this built in.[code]This appears to do something as far as sorting goes, but it doesn't sort it in the same way as clicking the column header. "startDate" is a property of an object in theDataSource by the way.

Actionscript 3 :: Is There A Hierarchical List Component For Flex

I will implement this myself if I can't find it but after 30 minutes of searching on the web I'm a bit surprised this doesn't exist. Basically what I need is a hierarchical list component like the finder app on mac. I want the same functionality as a tree component but displayed as each level having it's own list resulting in multiple lists that depend on each other.

ActionScript 3.0 :: Dynamic Charts With Variable Ranges?

May 5, 2011

Basically, I already have access to a tool (not flash, no source code available) that does all these complicated calculations based on dozens of variables and generates 2 charts/graphs based on those calculations. I'm making a "light" version that will only use 2 of those variables and a set of "standard values" that will act as a lead n/conversation starter.So, I have to display 120 different charts/graphs (60 pairs of graphs) that will be calculated by selecting variables from 2 different drop downs (one has 10 selections, the other has 6).Each chart is made up of 15 different data points that will be displayed on the chart with lines connecting them, so a total of 30 data points for each "set" of variables.

Here are my options:1) plug the numbers into the tool and grab a screenshot of the charts. Since the charts are ugly, I would have to physically re-draw each of the 120 charts to look the way it needs to in order to match the rest of the application2)...and this seems like the right way to go if I can figure it out...I can export the data points from the tool as xml, I use that to build arrays within flash and then dynamically plot the points and draw the lines. The only problem I'm facing conceptually is that the range on the y axis will change so I'll need to dynamically create the horizontal range line indicators, populate the range fields based on that range and keep everything constrained within the vertical limits of the chart.

Flash :: Flex 4.5: Tree - Make A Flex Tree Component Display The Children Of A Sprite In A Hierarchical Way

Nov 19, 2011

I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?

Flex :: Forcing Vertical Scrollbar Re-calcuation In A Hierarchical Tree Class Derived From Mx.controls?

Jun 28, 2011

I'm working (for my sins) on a Flex 3.3 project, which unfortunately cannot be upgraded to a newer SDK version at this stage, and have hit an issue with the custom hierarchical tree class (subclassing mx.controls.Tree) we're using. Excuse the spelling; the previous developer had a fear of dictionaries...

public class HierachyTree extends Tree
public function HierachyTree()
{[code].....

I'm using a solution somewhere between these two methods (basically, implementing ITreeDataDescriptor) in order to add live text filtering to the component, and it's working so far:

public class HierachyTreeFilteredDataDescriptor implements ITreeDataDescriptor
{
private var filter:Function[code]..........

The issue is that (with tree:HierachyTree) neither tree.maxVerticalScrollPosition nor the protected property tree.verticalScrollBar .maxScrollPosition updates when the search string is changed.I've tried calling invalidateList() and invalidateDisplayList() on tree — and calling invalidateDisplayList() and invalidateSize() on tree.verticalScrollBar — to no avail.

ActionScript 3.0 :: Flash Player We Use To Create Some Graphs And Charts Of Our Business Performance

Aug 6, 2009

I have this flash player we use to create some graphs and charts of our business performance. We use flash because we like those neat-o graphics and overall User experience.

The thing is that now I need to generate snapshots (i.e. images) of those charts every Monday so I can save them to disk.

Our flash player takes arguments at startup (or runtime) that specify the data we want to load and the date range, and we have LOTS of charts around.

I would like to know if there is any way to create these images in a batch, window-less process in linux. My goal would be to have a script that runs at 2am, automatically loads all the graphs say for the latest week, and creating PNG images for each. All this in one of our window-less (but with X11 libraries) linux boxes.

Flex :: Changing A Flex Movie To Use Runtime Shared Libraries And Losing Text In Charts?

Flex :: Parent Data Calculated From Children Fields In Hierarchical Data Structure

Jun 17, 2009

In flex 3 I have a hierarchical data structure. I would like to display the content of it in a tree. My problem is that I have nodes which data calculated from children nodes. How to structure the hierarchy to make automatic changes to those parent nodes, if their children's data changed? For example:

Every node has a warning flag. If some of the children warning flag changed to true, then the parent warning flag should change automatically set to true. A node integer field is the sum of the children integer fields, and if any of the children changes, the parent integer field "calculates" the sum immediately. Is there an easy solution wit good structuring changes happen automatically, or I have to make some custom functions?

Flex :: Update Hierarchical Data Provider In Advanced Data Grid During Drag And Drop?

Nov 11, 2010

I am trying to drag and drop hierarchical data in the same advanced data grid, and I would like the data provider to updated when the ADG is updated. (I want to be able to save and load this tree, so it is important that drags and drops are saved.)

[URL]

The sample app has an ADG showing hierarchical data as well as flat data. The first column of each datagrid shows the rowindex of the underlying data.

If you rearrange the items on the left ADG, the row indexes become unordered. If you click traceTree you see that the data provider is not in order.

On the other hand if you do the same on the right, the row numbers stay ordered even when the objects move around and if you click traceFlat, the data provider is in the order shown on ADG

My goal is to have the data provider order match the ADG order for the left grid which is displaying hierarchical data.

Flex :: Charts - LineSeries InterpolateValues As ZERO?

Jan 22, 2010

In a LineChart in Flex you can set a LineSeries to interpolateValues="true" what this does is connect missing values so you do not have gaps in your line. But what I would like is for it to insert 0's for the missing fields instead of drawing a direct line to fill the gap.

Is there a way to set it to do that?
