Re: [flexcoders] How to: Select range in Datagrid to set range in Chart?
Take a look here:
http://blog.kevinhoyt.org/2008/10/23/um-lots-of-flash-flex-and-zend-php-samples/in
the charts project.
Courtesy of Kevin Hoyt - he implemented a component that has a LineChart and
a DataGrid in a ViewStack (both linked to the same dataProvider), and a
HSlider to control zoom of the chart/grid. When you drag the HSlider to
define the range, both update to the selected range.

If I could simply define the first and last item selected in a chart

Chart?
Okay, I'll do my best to explain what I'm trying to do and see if
anyone can point me in the direction of a good url and sample -
What I would like to do is select a range of data within a Datagrid,
so lets say 10 items out of the list 20.
Than whatever is selected in the Datagrid, appears in chart. It is
merely a graphical way of filtering a date range of data. Currently in
my example, I select the beginning and ending dates. So all I would
require to modify this is to be able to pass along the the first and
last entry selected and define which column will be used.
Any ideas? Cheers.
[flexcoders] X-axis values in flex chart
Hey
I have a Flex LineChart with a lot of x values (around 300) - which
makes them not readable within the chart's container height/width.
Is there a way to make the chart display, say, every fifth value?
I am using:
mx:horizontalAxis
mx:CategoryAxis dataProvider={row} categoryField=x
labelFunction=formatHorizontalAxis /
/mx:horizontalAxis
The formatHorizontalAxis function formats unix-time into MM/DD/
using DateFormatter, and I suppose I could also implement it to return
every 5th value, but I was wondering if there is a better way to do this.
Thanks,
Sefi

Re: [flexcoders] X-axis values in flex chart
Hey.
I ended up calculating the number of tick labels to skip and used the
labelFunction to return the value every calculated value.
This works great - I have a label every 10th value, and all values are
displayed in the chart as they should.
Only problem is that the label font size is still very small (actually, it's
exactly the same size as when all labels are displayed).
I even tried to define horizontalAxisRenderers and in it a custom renderer
with a specified fontSize but tis didn't work either...
Does anyone have any ideas on how this can be accomplished? What I need is
to display every Xth label, with a readable font size...
Thanks,

I created a new Text class that extended Text.
I then change the textField.defaultTextFormat and call
textField.setTextFormat().
It works when I set it on creationComplete, but then when I remove and
add the editor again (which cntains the new Text), it takes all the
textFormat styles off.

everything is still there, EXCEPT for the format of the text, it for
some reason, is reset back to the original text, even though I have

Re: [flexcoders] Creating a Chart With 50,000 Data Points
Mark Easton wrote: It appears that Flex Charts cannot handle generating charts with large DataSets. We tried with 50,000 data points and it thrashed away without producing a result after 6 minutes. It was able to plot 2,000 points in about 25 seconds. What is the recommended approach for creating charts from large data sets. The best I can think of is to write some code that will reduce the data set in size yet still provide enough data to represent the graph accurately. Thoughts? LoD. Large scale datasets can work the same way computer graphics do. Users don't normally need to see every data point when a summary will do. Provide the user with the minimal amount of information necessary to understand what the data is saying and let them use the interface to drill down into specific areas. This works really well if you pre-calculate and cache the results on the backend (and predictive caching on the front doesn't hurt either). -Ricky

[flexcoders] modules or something else? + Mate
I have never used modules so I am not sure if what I am trying to do will work for them or not or maybe there is an easier way to resolve this issue. I have an app that has several documents. Each document is made of a canvas with an accordian in it. In this accordian I have two vboxes (thus to slides). The first vbox, which is shown on automatically, is a bar graph. The second vbox is a very heavy large custom component that is cpu intensive to create. Here is what I am currently doing, which freezes up my browser. In vbox1 I call this creationComplete=vbox2.createComponentsFromDescriptors() which means I am creating the children of vbox2 when vbox1's creationComplete event is dispatched. I do it like this so that when the user clicks vbox2 view it, its ready to view and they don't have to wait on it to load. The other way I was doing it was waiting for vbox2 to open and then creating the vbox2's children, which still causes the browser to lock up until it complete, but then they are also looking at a blank background. I tried to use an animation so they would have something to look at, but the animation stops because the browser is locked up do to CPU cycles be eaten up by my heavy components creation being so CPU intensive. I am not sure if moving to a module would solve this issue as I have never used them? Do they load like a flex appliation (progress bar)? And if I go with modules can through events like a regular component so my main app can listen for the events? I am using Mate so if that matters?
[flexcoders] HTTPService with mixed parameters

I need to call an HTTPService with POST method but I need to transfer

params to the service:

RE: [flexcoders] modules or something else? + Mate
If the cpu is bogged down by the creating of children, I don't think modules will help. Modules defer loading of the code for a view or component, but at some point you still have to instantiate it and create its children. I'd figure out what the bottleneck really is and work around it. If there's 1000's of children, but you can't see all of them or don't need all of them, create some, and create others in batches via callLater.

[flexcoders] Flex 2 charting license with Flex 3 sdk
We purchased the Flex 2 charting license. Now, we have upgraded to the Flex 3 SDK. We haven't (yet) purchased Flex Builder 3 as we/I don't use Flex Builder very much. I do command line/ant builds and editing with my text editor du jour. However, since upgrading to the Flex 3 sdk, we are now getting the data visualization... watermark. Is there something I can do with my flex 2 license.properties to get this to work? In Flex 2, there was some command-line stuff with charting-source.jar that I needed to do. Or, do I need to purchase/upgrade to Flex Builder 3 (Pro)? If the latter is the case, I think I read that I can just put the license in the flex-config.xml file. Is this true? Thanks, Jim

50,000? LOL. ;-) On a more serious note, I have to agree with Fotis and Ricky that 50K data points is too many, both from a (Flash 9 VM at least) performance perspective and probably also from an Information Visualization perspective (unless, maybe, your users have 300 dpi monitors). There are several standard interaction design and information visualization techniques which may be useful to you . . . 1) Aggregation (as already suggested, take 'N' data points, average them, and then only display the average value). 2) Filtering (by sliders on an axis, by date/time, by structured or open-ended queries, ...) 3) Progressive rendering (sample the entire data set at intervals of 'N', render those points, then go back and get the data which is mid-point between the original points, add the new points to the curve, repeat until desired resolution obtained--or on user demand) 4) Non-linear zooming (like idea 1), but allow user to zoom in on a section of the curve, when they do, add the additional data points to the curve for the zoomed-in region) On a more pragmatic note, you certainly _can_ plot more than 2,000 points. For example, I've personally used Flex to create charts with over 14,000 points in them, so I know that at least that number is definitely *possible*. However, the overall rendering time was (as I recall) over 3 minutes long. More troubling was the fact that the entire Flex UI become very sluggish once a chart that large was displayed. I've seen good chart rendering speed ( ~= 2S ) and no UI sluggishness, up to about 1500 points. I've also been able to render up to 6,000 points, but it took about 10S for the rendering and the UI started to become sluggish. From your posting, it sounds like you're not seeing those rendering speeds. I'd recommend that you experiment with how you are using the charting objects/API.

Re: [flexcoders] Re: Creating a Chart With 50,000 Data Points
What kind of charts are you displaying? I've had amazing success with scrapping the charting framework all together and simply drawing the chart programmatically. Yes, it's a bit more work, and yes it's only feasible if you don't really need a lot of the charting features that come in the framework. However, the performance difference is huge. The project I applied this on was for financial stock data, and using a custom drawn chart I mention above, along with the concept someone else mentioned by only showing the n-th datapoint interval depending on the overall range being displayed worked quite well. You're able to keep a consistent number of plot points (I've found 500-750 performs best) no matter what the overall range of data you're displaying. I say 500-750 performs best as I also had a horizontal axis slider which allowed for constantly updating data in the chart.

{
theURL += key.toString() + = +
params[key].toString() + ;

To send objects I would recommend using RemoteObjects.

RE: [flexcoders] Re: Creating a Chart With 50,000 Data Points
Hi Jim, Yes, LOL ... and it gets worse when we try to plot a graph for one year (about 500,000 observatons). We are plotting values received from sensors (eg temperature, vibration, humidity, gps location, gps velocity, wind speed, current, voltage, light). We take readings each minute. I have produced a dashboard which uses the following techniques: 1. Each sensor graph is in its own window ... so can be looking at 10 graphs at the same time for instance. 2. I average data to reduce the dataset size 3. I employ drill down 4. I have included a slider to look at reduced time frames The client rejected this solution. I did some tests in flex and found results similar to you Jim. When I tried to plot 40,000 points I gave up waiting for it after 6 minutes. 10,000 points took about 20 secs the first time (including reading from the local sqlite data store). The client and I have now agreed that: 1. If we have a large number of observations from a sensor and plot all of those on a graph over a period of time, then whatever optimisation we use to improve performance should produce an identical looking graph to the first. (I think that identical is probably to strong a word here) 2. We will add a confif paramter for each sensor such that the sensor readings can be changed to occur at multiples of 1 minute. For example, every 10 minutes. So, I will still end up with data sets to large for flex, and given that I want to display many graphs at once and will also be looking at representing many sensors on the one graph this contributes to the issue. So, I do need to sample the dataset somehow to make it work. But have to try to meet the goal expressed in point 1 above. I think a combination of your points 3 and 4 might be a good approached combined with some algorithm to ensure that my top level curve does not miss an max's and min's and as close as possible approximates a full detail curve. A few challenges there!

RE: [flexcoders] Re: Creating a Chart With 50,000 Data Points
Thanks Brendan, We are charting observations from a range of sensors and contact inputs. The contact inputs are a special case as they can only have 1 or 0 values. But the sensors include temperature, current, voltage, light, humidity, vibration, motion, gps velocity, gps location, wind speed, wind direction etc. The client does like the the charting features so he wants all of the flex charting cool stuff as well as the ability to see these charts. But that does not mean that I cant look at a combination of approaches. Its a good idea to look at coding a custom chart, and one I will look at closely. Yes I was thinking along the lines of having 2000 plot points. So in the case of a 3 month graph I would start with 120,000 points and need to reduce that to 2000.

I've had amazing success with scrapping the charting framework all together and simply drawing the chart programmatically. Yes, it's a bit more work, and yes it's only feasible if you don't really need a lot of the charting features that come in the framework. However, the performance difference is huge. The project I applied this on was for financial stock data, and using a custom drawn chart I mention above, along with the concept someone else mentioned by only showing the n-th datapoint interval depending on the overall range being displayed worked quite well. You're able to keep a consistent number of plot points (I've found 500-750 performs best) no matter what the overall range of data you're displaying. I say 500-750 performs best as I also had a horizontal axis slider which allowed for constantly updating data in the chart.

LOL. ;-) On a more serious note, I have to agree with Fotis and Ricky that 50K data points is too many, both from a (Flash 9 VM at least) performance perspective and probably also from an Information Visualization perspective (unless, maybe, your users have 300 dpi monitors). There are several standard interaction design and information visualization techniques which may be useful to you . . . 1) Aggregation (as already suggested, take 'N' data points, average them, and then only display the average value). 2) Filtering (by sliders on an axis, by date/time, by structured or open-ended queries, ...) 3) Progressive rendering (sample the entire data set at intervals of 'N', render those points, then go back and get the data which is mid-point between the original points, add the new points to the curve, repeat until desired resolution obtained--or on user demand) 4) Non-linear zooming (like idea 1), but allow user to zoom in on a section of the curve, when they do, add the additional data points to the curve for the zoomed-in region) On a more pragmatic note, you certainly _can_ plot more than 2,000 points. For example, I've personally used Flex to create charts with over 14,000 points in them, so I know that at least that number is definitely *possible*.

I have an app that has several documents. Each document is made of a canvas with an accordian in it. In this accordian I have two vboxes (thus to slides). The first vbox, which is shown on automatically, is a bar graph. The second vbox is a very heavy large custom component that is cpu intensive to create. Here is what I am currently doing, which freezes up my browser. In vbox1 I call this creationComplete=vbox2.createComponentsFromDescriptors() which means I am creating the children of vbox2 when vbox1's creationComplete event is dispatched. I do it like this so that when the user clicks vbox2 view it, its ready to view and they don't have to wait on it to load. The other way I was doing it was waiting for vbox2 to open and then creating the vbox2's children, which still causes the browser to lock up until it complete, but then they are also looking at a blank background. I tried to use an animation so they would have something to look at, but the animation stops because the browser is locked up do to CPU cycles be eaten up by my heavy components creation being so CPU intensive. I am not sure if moving to a module would solve this issue as I have never used them? Do they load like a flex appliation (progress bar)? And if I go with modules can through events like a regular component so my main app can listen for the events? I am using Mate so if that matters?

RE: [flexcoders] Re: HTML IN FLEX
AIR includes a very complete HTML+JavaScript engine (WebKit), but this engine is much too large to include as part of the ordinary Flash Player. Flex 3 components such as mx:TextArea which have an htmlText property are based on the Player's flash.text.TextField class, which supports a small and nonstandard subset of HTML. See the htmlText property of TextField in the Language Reference for a list of what tags and attributes are support in htmlText markup. Adobe is developing a new Text Layout Framework (TLF) which works with the new Flash Text Engine (FTE) APIs in Player 10. (It will be used in Flex 4.) TLF will not support all of HTML, but it will be more capable than TextField's htmlText.

There are several standard interaction design and information visualization techniques which may be useful to you . . . 1) Aggregation (as already suggested, take 'N' data points, average them, and then only display the average value). 2) Filtering (by sliders on an axis, by date/time, by structured or open-ended queries, ...) 3) Progressive rendering (sample the entire data set at intervals of 'N', render those points, then go back and get the data which is mid-point between the original points, add the new points to the curve, repeat until desired resolution obtained--or on user demand) 4) Non-linear zooming (like idea 1), but allow user to zoom in on a section of the curve, when they do, add the additional data points to the curve for the zoomed-in region) On a more pragmatic note, you certainly _can_ plot more than 2,000 points. For example, I've personally used Flex to create charts with over 14,000 points in them, so I know that at least that number is definitely *possible*.

I've seen good chart rendering speed ( ~= 2S ) and no UI sluggishness, up to about 1500 points. I've also been able to render up to 6,000 points, but it took about 10S for the rendering and the UI started to become sluggish. From your posting, it sounds like you're not seeing those rendering speeds. I'd recommend that you experiment with how you are using the charting objects/API. My experience was that I was able to see some very noticeable speed-ups simply be optimizing how I called the charting API (especially w.r.t. how I loaded the series data). In particular, if your charts are interactive, try to cache anything you can that doesn't necessarily change during an interaction (i.e., axis objects). Last thought: the new Flash 10 VM (Astro) has support for larger bitmaps and also can now do hardware-based rendering, apparently. I haven't tried either of those features myself, but using the v10 VM _might_ be another way to get a performance boost, etc. Good luck!

[flexcoders] Re: May I save BitmapAsset instance to database?
Your question is a bit vague, but I'll try and be of some help. You can use the ImageSnapshot class to get the ByteArray the backs your image. Then you can store those bytes in a database and pull them up later. If you're building an AIR application and saving the image to a local database you'll want to read up on the SQL utilities available to you here: http://livedocs.adobe.com/flex/3/langref/localDatabaseSQLSupport.html If you're building a browser app you can pass the ByteArray to a webservices or a remote object that will store the image in a database. http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_4.html If you can be more specific about your problem, we can provide more help. --- In flexcoders@yahoogroups.com, markflex2007 [EMAIL PROTECTED] wrote: Hi, I create a BitmapAsset instance from image class and I want to save it to database and other people can see the image when he read out BitmapAsset instance from database.

[flexcoders] Is it this difficult to purchase Flex in south east asia?
Hi.. I'm sorry if this question goes a little bit out of topic. I live in Indonesia and would like to purchase Flex 3, so I contacted a local reseller/distributor (this distributor does listed in the Adobe's website). FYI, there's no Adobe representative here in Indonesia, Singapore is the nearest. Short story, I paid full for my purchase in 22 Sept, and they promised at least 2 (two) weeks of delivery time. But until now (so it's been almost 2 months), they were still unsure when they can deliver Flex. My last contact with them was last week (10 Nov) and they asked me to wait about 3 or 4 weeks more. I don't quite understand what's their problem and what cause the delay (they only said need more time to deliver) Can you imagine, 3 months to get a software that is suppose to be already released? I wanted a full refund and think of buying online, but they said my order were already processed through Adobe Singapore. Can anyone help me? should I wait again? -- / i w a n

[flexcoders] Does Smart Serach like 'You tube' does possible in Flex ?
Hi Guys If you go to You tube and when you start typing stuff then you get suggestions for the related text you types. I have requirement something like this. I pulled the data in my list box and we have to make it search able like if user starts typing in the text box say 'Adobe..', the list containing the original data starts getting filtered with the entries starting with name 'Adobe' . if the user does not enter anything in the text box, he/she will receive the original list with the complete data. My question to you genius guys is that is it possible in Flex 3.0/AS 3.0 or should i go through some other language. I read somewhere that it can be done using AJAX but I like to achieve this functionality using Flex. Please let me know if this is doable , any help/links will also be appreciated. Thanks Anuj

[flexcoders] AIR Cairngorm Application Command Architecture
I have question about setting up an air application architecture using cairngorm commands. So the application has very complex calculations that have be done in steps and I am not sure the best way to lay them out in cairngorm. A general example is as follows: there are 5 different calculations which can be done. Each of these calculations involves multiple steps. Each step may have to lookup information in the local database. Some of the steps are reused from calculation to calculation. So I was thinking of each calculation being a command and then the steps would be helper classes that use delegates to get the information from local database. Any thoughts would be great. Thanks in advance.
RE: [flexcoders] JavaFX and Flex how do we compare?
I would be curious to find out how others view the platforms, especially from the standpoint of external application developers, but having been on the inside of both of these projects, here are some points of comparison. I'm attempting to be objective here and just point out some of the areas to consider. But since I used to work at Sun on Java/JavaFX and now work on the Flex team at Adobe you should filter appropriately. - Maturity: One of the reasons that you haven't heard much about JavaFX to date is that it's actually not yet released. Supposedly this will happen in the very near future, so maybe we'll all hear more about it at that time. - Language: Although many of the underlying capabilities of JavaFX rely on the Java SE platform, JavaFX itself is based on a new scripting language (not Java, not JavaScript, not ActionScript, but a new scripting language entirely). One notable differences between the languages of JavaFX and Flex is that Flex uses MXML for its declarative aspects, and ActionScript for the programmatic aspects. The JavaFX language combines both of these elements, having aspects of declarative and programmatic in the same code. - GUI capabilities: Both platforms offer GUI components, graphics, animation, and databinding capabilities, thought the platforms differ widely in syntax and capabilities of these different features. - Tooling: Most of the tooling so far announced for JavaFX are more on the code developer side; editing plugins for NetBeans, plus export plugins for Illustrator and Photoshop (they produce PNG files from the layers in the project). On the Flex side, there's the FlexBuilder IDE and the in-development tools such as Flash Catalyst for designer/developer workflows and FXG roundtrip import/export from/to the CS tools including Catalys for the graphics tags in the Gumbo release of the SDK. - Runtime availability: The availability of the JavaFX runtime is basically that of the Java platform (if a user's machine does not have the proper release of Java (I believe it will require the latest updated 10 release), they will need to download/install it). The availability of Flex is basically that of the Flash platform of the appropriate version (e.g., Gumbo will run on FlashPlayer 10). Chet.

Re: [flexcoders] JavaFX and Flex how do we compare?
Thanks for that info Chet, you're definitely in a unique position to offer insight. Would I be right in saying that compared with FX Script (ie, without writing Java2D / Swing code), AS3, Degrafa/FXG and MXML provide a lot more power in terms of custom component and skin creation? This is the way it seems, but that could be completely the fault of Sun bungling their PR as usual ;-) I'm also interested in the differences and similarities between JFX's bindings and those supported in Flex if you can find the time to elaborate on the subject.

[flexcoders] Re: How do they do that (Flex video)
No it's not OK ;) When a company has different file formats then it's really sad and unfortunate to have to rely on third party tools for conversion between those formats - if for no other reason then integration and overall better experience. My laymen understanding is that FLV is a streamable video format and like you said SWF is like an exe. Well actually it's more like Java byte code in that it is a stream of byte code that is only understandable by the Flash Player. If you look back through some of the responses or maybe they are on my other post, you will see that at least one person on this forum has suggested using SnagIt or some other screen capturing tools. No, indeed it is not OK if folks who are evidently at least dabbling with Flex and there they are suggesting third party screen capture tools. Not only is it not OK but it is quite sad that Adobe, who is smack deep in this space, has left even one developer thinking of resorting to such band aids. I for one am disgusted by it and only because they know the best how to play a SWF file and how to capture the video stream that comes out of it. Enough said on my part. P.S.

Here is my code: mx:DataGrid id=CertDG width=528 height=60% editable=true mx:columns mx:DataGridColumn headerText=Name dataField=cert_name/ mx:DataGridColumn headerText=Issuer dataField=issuer/ mx:DataGridColumn headerText=Achieved dataField=date_achieved editorDataField=text mx:itemEditor mx:Component mx:DateField formatString=DD-MM-YY yearNavigationEnabled=truetoolTip=Format:DD-MM-YY/ /mx:Component /mx:itemEditor /mx:DataGridColumn /mx:columns /mx:DataGrid Thanks for the read, timgerr
[flexcoders] Re: How do they do that (Flex video) ?
have been more constructive by pointing me towards creation of FLV files which are uploadable onto YouTube. I did. I must have missed it in the rest of your non sense ;) Surely Adobe would not allow us to find ourselves in a situation that would require third party conversion utilities just to convert between Adobe SWF and FLV formats. If there are good free tools to do it, why should Adobe bother compeating unless it can make a killer advantage. Is integration and a resulting much, much better experience not enough of a reason? As a matter of fact, good part of what Adobe does so well is already done in pieces elsewhere. The reason why Adobe does it well is in great part due to nothing more than better integration and a resulting better experience. If Adobe wrote such a SWF to FLV converter then they could offer it to YouTube and other sites so that they could accept uploading of SWF files, on which they would then do PERFECT conversion into FLV or some other format. There is another thing Tom that you totally fail to recognize and that is the quite poor quality of most of the videos that are currently up on YouTube. A lot of quality is lost in the process of using various settings of frames per second and Kb or Mb per second, that may or may not match what YouTube uses and then one's video ends up going through yet another conversion, resulting in yet another decrease in quality. Giving YouTube a perfectly beautiful looking SWF presentation and letting them convert it to FLV with whatever settings suit them the best, would most likely result in the best possible video quality. When all is said and done Tom, be assured that most of the folks out there (most of them not being technical) can not tell nor figure out why ADOBE FLASH MOVIES look so bad on YouTube. Most of them know how to right click on one that they are watching and BINGO, we know what they see will UNFORTUNATELY in most cases cause them to erroneously think that FLASH IS CRAP FOR VIDEO. Surely they would do that, if for no other reason than to keep us off the slippery slope of even contemplating exploring what MS and Silverlight might be capable of and from calculating just how long it might take, either way, before MS ends up eating everyone's lunch. ;) If people want to go in the direction of spending more money, as opposed to less money, they should feel free to do so. We'll see them back again in a few years :-) Sorry Tom but since (with a statement like that) you seem to know very little about how Microsoft operates, I will explain it to you. Time is the only thing that is on Adobe's side. Eventually, Microsoft will end up eating everyone's lunch, at least on the desktop. It causes me a lot of pain to say just that but it is true. While they have a lot of catching up to do, within a couple of years they WILL catch up to Adobe - technically speaking. With another 2-3 years, they will catch up in the field as well - in terms of deployments. Tom, like it or not, there will not be anything that will be more beatiful then an end-to-end .NET code (C#, VB, take your pick) that stretches from the clients/devices and all the way through the servers and into the database itself (stored procedures). Unfortunately, they WILL end up eating everyone's lunch because of the beauty and a much, much better developer experience due to such an end-to-end integration. Just the type of lousy integration, a small piece of which I suggested earlier. P.S. You just happened to be the closest official one on my path of frustration. Please take my comments constructively and not at all personally, even though that might end up being hard to do, at least from a first reading. And thanks for replying.

[flexcoders] dataGrid effciency
hi everyone, i used dataGrid to display a list of real time data. when i finished it, i found it is slow. the DataGrid has 13 DataGridColumns, every column almost nest a ItemRenderer. i had to do this to meet the requirements of pattern. the data update every second, and i need to change the components’ style in some columns following the data. as i know these two aspects will cost large calculation. who konws how to optimize it or other ways to achieve. thanks
[flexcoders] Re: dataGrid effciency
Hi, The biggest performance culprits with a DataGrid, or any of the ListBase components, is the itemRenderers and the size of the dataProvider. You can optimize the itemRenderers by using UIComponent; see Alex's blog. And depending on how many items are in the dataProvider, you could see performance issues there as well. If you are performing any calculations you might look at ways to tighten up the code. With a one second refresh, you might be asking too much of the UI. -TH --- In flexcoders@yahoogroups.com, Fu Di [EMAIL PROTECTED] wrote: hi everyone, i used dataGrid to display a list of real time data. when i finished it, i found it is slow. the DataGrid has 13 DataGridColumns, every column almost nest a ItemRenderer. i had to do this to meet the requirements of pattern. the data update every second, and i need to change the components¢ style in some columns following the data. as i know these two aspects will cost large calculation. who konws how to optimize it or other ways to achieve. thanks
