Flex :: Charts - DataVisualization Charting Components Rendering Labels On Build Server
Apr 6, 2010
I'm having a problem with labels disappearing on Flex's datavisualization.swc charts that are built on our build server via ANT and the Flex 3.3 SDK. I've made sure that our license is applied properly on the build server (hence no water marks), and I've made sure the exact same datavisualization.swc was copied from my dev machine into the Flex3.3SDK/frameworks/libs directory.
Could it be a font problem? (Though we're really only using default fonts.) Here's the problem, missing axis labels on the build server Here's how it's supposed to look with labels (taken on my local development machine)

I have a professional license of Flex 3.3. This allows me to create applications using the data visualization components (charts) without watermarks. However, all of release builds (test, production, etc) occur on our build server.
The build server only has the Flex SDK installed (not full Flex Builder). As a result the SWFs compiled with this SDK contain watermarks on all the charts. How can I apply a Flex Builder Professional license to the build server to remove the watermakrs w/o installing Flex Builder?My build environment is Flex SDK 3.3 + CruiseControl.NET + NAnt.

I have multiple line charts in Flex Charting (3.x). The charts (and number of charts) are being dynamically generated, and are either of "type A" or "type B." The type of data on the Y-axis is different for type A then it is for type B. The x-axis is time.
Each chart is placed in its own VBox (with a few other things) that make up a larger canvas of the Type A or Type B. This VBox is given an absolute X position. It is very high priority that the different charts line up, so that comparisons (in time) can be made.
What ends up happening is that the vertical axis for some charts takes up more width then others, so the charts are no longer aligned in time.

I have a chart that uses a DateTimeAxis for the x-axis and a renderer defined for it. I also have a function defined for the label on the axis but I am not able to get the labels to show.
Trying to print out a static time to test working.
private function timeAxisLabelFunction(obj1:Object, obj2:Object, axis:IAxis):String
{
return "9:30AM";
}
[Code]....
Apparently, the font family I was using doesnt support a font style that is used in the renderer. Not sure what style attribute it is yet.

I have a line chart that sometimes contains a number of data points. I have solved how to prevent the horizontal axis from displaying too many labels using custom label functions and data functions. My problem is forcing the AxisRenderer not to scale down my labels.
I'm using the labelRotation property so the canDropLabels and canStagger properties are not an option.

Why do I need to do add extra namespace declarations (below) in a Flex 4.1 "MX only component set" project to get it to compile within Flash Builder? (It says mx:LineChart cannot be resolved when a chart is added via Design View, and datavisualization.swc is referenced.)
Is there a way I can get this to compile without adding these special xmlns:charts, xmlns:series and chartClasses to the declaration? (If I just leave the default namespaces and use mx:SomeChartComponent, it doesn't compile.)

I have developed a flex application using the data visualization components. I am now trying to optimize the application and one of approaches I am trying is to use Runtime Shared Libraries.I have configured Flex Builder to deploy with Runtime Shared Libraries and have added the .swz file for the framework, datavisualization and rpc share libraries. After deploying, my application loads, however my axis values within each of my charts are missing. The axes themselves are shown, however they do not have their label units displayed. The series themselves are displayed too.I have tried this using the 3.4 SDK and also the 3.2 SDK within Flex Builder. I also tried compiling flex using the mxmlc ANT tasks and got the same results.I made sure that the framework RSL is getting loaded first and I also made sure that the global flash cache has been cleared before I tested.I can see from my access logs that the .swz files are getting loaded the first time I make a request for my application, so I am confident that I properly cleared the flash player global cache.
Does anyone know why my axis values would be missing only when I deploy with RSL??? Switching back to Merged mode, my application works fine and it is only when I deploy with RSLs that I get the issue.I have also tried to compile using only the framework RSL and not the datavisualization or rpc RSLs (keeping them in merged mode) and I get the same results, no axis values.

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. It seems that the screencapture that AlivePDF took to generate my pdf was too small.I am trying to get a chart from a sample to work with sample code for using alivepdf that I picked off the web.[code]

I build a web site in flash using lables and one of the lables is video. I put video in the video label. When I click to go to anyother label, the video is still playing. what code I would write when I click off the video label the video would stop playing. It sounds like some if statement.

I have a list component that has hard-coded labels on it (for testing). I then rotate the list component 90-degrees and notice the text disappears(during design time).
I test the file and the labels do not show up also during runtime.
I can get the labels to show if I rotate the component back to its' original state.

I am trying to build a flash player for my company's Shoutcast server, and have seen a few articles about it on the 'net, including this SO question here. However, I can't seem to get the audio stream to actually play. It seems to be connecting alright, but calling stream.play() doesn't seem to do anything.
public function stream() {
private var url:URLREQUEST = "my.domain.com";
private var sStream:Sound = new Sound();
sStream.load(url);
sStream.play();
}

Is there anyway where I can pass the Array values (not the array collection values) to the Bar charts or column charts using flex 3.5...
here is the thing i want:::
I have array values like this,,
array1 = [23, 49, 40, 239, 20, 80, 39,49,120, 24, 31,41];
and i want to show these values on the Yaxis and months on Xaxis....
I have two Qns,
1) how can I pass this array to Bar chart or column chart.
2) how do I need to show months on Xaxis. beacuse I'm asking this regarding, I have kept a filters that even if we want to see some months or a particular months or perticalar span of months... there on Xaxis it need to change the months dynamically depending on the filters..... (for ex, on Xaxis the values should be (Jan, Apr, Jun,Oct) if i select the 3 months period filter....)
I have written a logic to collect the values of those particular months into an array, but not understading how to pass this array to Bar chart,, beacuse there I don't know what Xfield and Yfield to be given....

In TFS 2010 build, I have a new build and I want to call an ant script that builds Flash. How do I call the ant script? Also How can I compile the Flash directly? I've seen the Power Tools and this question but it doesn't help me as we don't have TFS 2008. I can't find any documentation on how to use the power tools except the 1 sentence on the bottom of download page saying to create your build the old way and import it (which isn't very helpful). I've installed the power tools on the agent computer but I don't see any new options in the Toolbox when I'm designing the build flow.

I just started working with ant a few days ago. Right now I have a general buildall.xml which should call each project's build.xml. Because some projects depend on each other, I need to rebuild some other projects which depend on it. This isn't a problem--I'm just setting the depends property of the target. However, ant is always building the dependencies, even when the files haven't changed.Let's say project1 has no dependencies; project2 depends on project1; project3 depends on project1, 2; project4 depends on project1, 2, and 3; and so on.I could hack a solution which looks at project K, and checks if project 1 .. project K have updated files using uptodate. If so, then run the target. This is messy and appears unnecessary.
What is the cleanest way to implement this?EDIT: So I decided to just hack in a bunch of targets, "check_projectK" where it does the uptodate checks on all of its source files, its build file, and the build files of the 1 .. K-1 projects. Due to dependencies, this is always handled correctly. However, this is still a large amount of copy and paste for a large workspace.

Do you have any recommendation for a free 3D charting library in Flex. To be more precise, I only need to draw surface (for now). Basically, I just need a chart that displays three axes (one should be timeline, and two should be linear axises) and the surface.
From what I have seen so far, two most popular free Flesh 3D libraries are Papervision3D and Away3D. Also, I've found one IBM library - ILOG Elixir that looks really nice, but it's proprietary (although, I haven't seen any surface examples for Elixir neither). From what I have seen, Papervision3D and Away3D should do much more then 3D charting, but I haven't seen any examples on how to draw surfaces in any of them (except this line chart in 3D: [URL]

DataTips in flex charting are a poorly documented and little-understood feature.There are three parts, the DataTip (by default a box with text inside), the DataTipTarget (default bulls-eye circle over the series' point), and the Callout (the line from dataTipTarget to DataTip box).How are these three elements created/drawn and how can they be customized?

I am trying to create some charts in Flex/FlashBuilder 4.5The issue I have it that the information I wish to display is the number of events within an area. I am using HTTP service to access a rails controller which is returning an XML list of the events.I need to figure out how to chart the number of events, eg number of records returned. There is no numeric value within chart, as there would be if I was charting sales or prices for example.

I'm relatively new to flex, and I'm developing a web app that needs to plot relatively large data sets (e.g. 20,000 pts divided among 8 separate curves) in a line chart. Flex built-in chart components render too slowly.Would javascript line chart render faster than Flex line chart? If so, is it possible to use a javascript-based charting solution instead of flex component, within the Flex application? Or, is this an impractical (or crazy) idea? Anyone doing this out there? How simple or complex is it?I'm hoping it's relatively easy to integrate a pre-developed solution like EST JS, HighCharts, etc. to simplify development.
