I am a newbie in flex.
Latest task is to generate a graph or a netwrok based on the data input.
What is the best way to do it. Also when clicked on a node of a network it should show the associated data with that node.
Hope to get some help soon!
Thanks,
Kartik
You need to get a license to flex builder pro to use the Flex Graphing components. You can see what components are available with example code from this link
http://examples.adobe.com/flex3/componentexplorer/explorer.html
Open the data visualization folder to get to the charts.
You could also try:

Are there any beginner-friendly tutorials to display graphs in the way Knowledge graph has been done?
I have the data is JSON format presented from a graphdb
For eg:
The closest I have found so far is Gelphi. Which also can be integrated with unity to produce a 3d Graph like this one https://www.youtube.com/watch?v=h_arRCf73Kg.
Then there is https://cayley.io/
https://n0where.net/opengraphiti-data-visualization-engine/
There is also https://www.maana.io/knowledge-platform/platform-capabilities/#maana-knowledge-graph . However, i have not tried to use/download their platform.

Finally, I am working myself on learning unity to build a simple GUI which a user can identify nodes and edges and entities easily and move them around. So instead of just reading from a data base, also write to it through a UI.
I decided to use Drupal for a project. I am having some difficulties so please kindly help me.
I want to generate a table containing different calculations.
I want to generate a chart using the data from the table. If possible.
I tried before with view aggregation but no luck so far
I can't use google chart . Machine don't have access to internet.
Please see the attached image for info
Using Charts in combination with Highcharts is for sure an option that does not require an internet connection. However you'd have to check The license terms to see if you qualify for a free license (at no Cost). Refer to Steps to create charts using the views UI for step by step instructions.
There are some other modules available also, which also facilitate the creation of charts, and which might be considered as a possible alternative to the charts module. Checkout the Comparison of charting modules I creatief, for more details about them.
I have been goggling a lot to find anything that can help me with link-based data visualization in Flex 4. something like below screen shoot (made using Ravis).
Where user can drag these nodes, without removing the links and on double click of any node we can set some properties for that particular node.
I found this Ravis (Birdeye), but not much of examples and support is available for that. I was wondering is there any thing already present in Flex 4 or anything that might help?
Thanks
Try the components from Kap IT Lab They have been around for a long time, and you can test them for free. They also have a free community edition, which may suit your needs.
I am not associated to them in any way. You can see demos of their components in the Tour de Flex application.
So basically what I'm trying to do is make something like this:
http://store.kapit.biz/demo/treemap/prod/index.html#
I've searched long and hard to find a site that would show me some pseudocode (at least) or an algorithm as to how to implement this type of application. But everything I find are only applications that take in data and do all the work for me to create the graph. I need to actually create it for myself, just a simple one for now. Does anyone know where I can find this? What I want it to do is take data from a database and use it to create the treemap, then express it in a GUI like in the link above. If any specifics are needed I can provide it. I'm trying to do this in Flash Builder using Flex and using ColdFusion as the backend. Thanks!

Is there a way to export a flex graph to excel? Thank you in advance!
While I've never tried doing this myself, it looks like some other folks have solutions for exporting to Excel.
Check out:

The following might help if you are using a Flex app served from a Web app with a Java backend.
Flex includes some nifty out-of-the-box functionality for capturing images. If it suits your requirements to simply take a snapshot of the graph and slap it into an Excel document, it should be possible.
Here's an example for grabbing a snapshot. The bytes could conceivably be streamed back to the Web app. Then you could reconvert the bytes into an image object and use POI to add the image to Excel.
Another option might be to take the same underlying dataset used for rendering the chart in Flex and just build the chart in Excel. That assumes that the chart does not need to have the same look and feel as the corresponding Flex version, though. I've never used it, but the jXLS tool looks like it might provide Excel chart-building capabilities.
