We have the WebApplication portal. We are generating the stats survey, which needs to displayed on graph. We have started using HighCharts. As a requirement analysis, I would like to know, what are the other alternative for Charting and Graphing. Can you advise/discuss, which is more efficient,effective way of charting? What are the pros and cons for each platform? Any more other alternatives ?
View 1 RepliesI am searching for a free charting library, either in Java, JS, or Flash, that allows for drill-down type interaction. An example of this sort of behavior can be found in the trends section on mint.com. JFreeChart seems like the generally recommended choice for charting purposes, but from a little browsing of their API there doesn't seem to be any obvious way to detect mouse clicks on a particular slice and change the chart in response.
Any advice on how to handle this sort of behavior using JFreeChart, or if this is not possible any recommendations for other libraries that do support this behavior?
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.

But when I'm trying dynamically create horizontal and vertical axis then I'm getting extra axes. I believe this is Adobe bug. How I can fix this behavior?

Is there a flash widget that can read, say JSON/XML data, and create an interactive network graph that which users can drag nodes around? I'm not looking for software that creates static images... but something more dynamic, like "heavier" the node, the bigger it looks. That kind of Flash widget.
View 3 RepliesI want to make a graph. Specifically, a graph of a normal population distribution.I think (please correct me if I'm wrong) that the best way for me to do this is to use two arrays for coordinates and use the lineTo function to connect the dots:
- An Index array up to about 300 as the "x-axis"
- A Second array to represent the "y-axis" created using the formula for normal population applied to each entry of the index array
So I need to create these two arrays in FMX. the first array i think should be created with a For loop: for(i=0;i<a.length;i++){} The second array somehow applying my formula to each entry in array 1.I believe my methods are correct, but I am having a great deal of trouble getting the AS down properly and I can't find many good sources on it.

I am writing a library in ActionScript 3 which needs to call functions in JavaScript. Since it's a library, there is no AIR, and thus HTMLLoader can't load an HTML containing the JavaScript.
how to call JavaScript which is not in an HTML window?
Lets say I pick up a pure Javascript library... one that doesn't rely on the DOM in any way.Now, lets say I want to take that library and us it in Flex. Is there any good way to do this? I can't simply include the Javascript, as it is not close enough to ActionScript to compile... but is there a good converter that will do it for me? Take the Javascript prototype style classes and convert it to ActionScript classes?
Lastly, I don't want to use the Browser for this.I know that I can always use ExternalInterface to access the browser, but I am not always running my Flex app in the browser... sometimes it is Air, and sometimes it is in a PDF.
I'm involved in writing a Flex/ActionScript library and in the future I will be involved in writing the same library in JavaScript. Rather than writing a library in each language and having to maintain them separately I was wondering if it was possible to:
1) Write the code in one language and share the code into the other e.g. Write the code in JavaScript and use the same .js files in ActionScript
2) Write the code in one language and perform a conversion into the other
I know it's possible to communicate between Flash/ActionScript and JavaScript but I'd like to avoid the overheads in using the technology bridge so this isn't really an option.
How do other people deal with writing and maintaining libraries that do exactly the same thing but in different languages? Specifically how do people do this between JavaScript and ActionScript?
Currently I'm searching for a free solution to simple edit some photos at the users browser. Resizing and Cropping would be mandatory. I'm not searching for an online service (for example SUMO or PIXLR which are great), because I want to include the software into a WYSIWYG Editor. JavaScript would be really nice, but it would have to work in IE 8. Pixastic is a great example, but works only in modern browsers (not IE 8 :-/) Maybe setting up some kind of image processing service with ImageMagick and communicating with it through AJAX could also be an solution? Has anyone gained some experience with such a solution?
View 2 RepliesThis isn't another one of those "How can I record audio in the browser?" questions... I know that the HTML5 Stream API is around the corner and Flash can already access the user's microphone and camera. I'm simply wondering, as a Javascript developer with little knowledge of Flash, if anyone has developed a JS library that hooks into Flash's device capabilities for recording but sends the results back to javascript (presumably using ExternalInterface).
In other words... libraries like SoundManager2 utilize a Flash fallback for audio playback, but they don't seem to allow for recording. Has anyone written a JS library that uses an invisible Flash movie to allow audio recording?
I'm writing an Adobe AIR app using plain HTML which needs to upload photos to Facebook. I don't think Facebook's JavaScript/Connect library includes photo uploading functionality, but their ActionScript library does. However, I'm having trouble loading the ActionScript library into the HTML page.
Adobe's documentation describes the process of loading ActionScript libraries into HTML AIR apps, which I tried using the compiled Flash library available here (specifically, Facebook_library_with_AIRConnect_v3.4_flash.swc). So my page looks something like:
<html>
<head>
<title>Hello World</title>

Is the compiled library file I used the wrong one (do I need a .swf instead of a .swc)?If so, do I need to create my own compiled library somehow from the ActionScript source?Is the namespace I'm using incorrect? (in addition to com.facebook.Facebook() I tried .Facebook(), .fb.Facebook(), .facebook.Facebook(), etc)Should I just give up and try to learn Flex instead?
My PieChart has a dataTipFunction property
My PieSeries has a labelFunction property
I would like my dataTipFunction to return the same string that my labelFunction returns.

name some API for charting in flex except AmChart.I want a good API as i am facing too much problem with AmChart API.
View 1 RepliesDo 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 want to emulate the datatip feature on google finance here URL...whereas the datatip does not appear over the chart when you hover over, but instead is anchored in the top right header of the chart. How do I go about doing this? Thx in advance!
View 1 RepliesIs there a free web control (serverside php or clientside flash or javascript) that can take a set of datapoints with timestamps (possibly with gaps or at irregular intervals) and draw a chart that would automatically scale the date axis? If there are a few datapoints hours apart then the chart would draw each datapoint. If there are thousands that span a year, it would draw month grid. If there are gaps - it would interpolate.
View 1 RepliesI 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.
View 1 RepliesI 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.
When I use radius property in Flex plot chart It causes a warning says radius has been deprecated, use radius style There's no online documents about this warning. How Can I use radius style ?
View 1 RepliesI have a LineChart that contains multiple series, both LineSeries and PlotSeries, and I have a custom dataTipFunction set for the chart. However, I only want data tips displayed for line series, not the plot series. I have tried returning null from my format function, but that just displays an empty box. I have also tried disable mouse events on the plot series (by setting both mouseEnabled and mouseFocusEnabled to false), to no avail. Is this even possible?
View 1 RepliesI'm trying to plot data from several entities over time. Each entity will have its own line, so there will be several lines. Each line will be connected, but it's important that dots are drawn to represent data.
I'm aware of the linked bar chart, but at initial inspection, I can't seem to find one that offers me the ability to draw the dots. Anyone knows which library has this? I'm open to PHP, Flex, degrafa, whatever else that gets the job done.
Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!)
SWFUpload - latest release 03/2010, documentation
fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?
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 been working on a charting flex document listing repository statistics for work and it can be seen here -http [url]...orialJorum.swf Unfortunately,my hard drive died last week and the MXML source files were wiped(I know I should have backed it up). As I cant really afford paying $80 to decompile to get the MXML script, I wondered if anyone could do it for me as I put many hours into that piece of work. I have tried using the demo version of SWF Decompiler and Trillix but unfortunately they only give you the component code and not the <script/>
View 3 RepliesI'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 two requirements for a flex charting component:
1) The grid lines should always remain fixed to a scaling I define using an array of data. Something like a graph paper sheet.
2) Plot multiple line series data over this grid.
How does one get complete control over the background grid lines? I have tried a combination of annotation elements and setting the linechart background elements. If I get the grid right, I can't plot over it (Probably due to the scale). how would one go about designing a graphpaper like interface for linecharts in flex/actionscript?
