Hi all,
I started to develop an extension for graph visualization based on the Graph Dracula Library, using Raphael: http://www.graphdracula.net
This seems to be an interesting topic. First of all, what is the best data representation of graph data in a relational QlikView world? Second, there are a lot of limitations using those JavaScript libs. I've tried some before (D3.js etc.) but Dracula seems to have the simplest interface for my use case.
What is your opinion?

Hi Ralf,
Can you please attach the Document with explanation. That one will very much helpful for me
Hi Ralf,
Thanks for a really nice extension! One question; are there any limits on how many nodes and child nodes the extension can plot? When will it become difficult to use?
Best regards

Hi Marianne,
I set the limit to 2000 lines for the extension in Definition.xml. This means it will paint 2000 edges maximum, theoretically 4000 nodes max. I guess it will get very slow with more then a hundred nodes or so because of the auto layout rendering (GraphDracula). For the SigmaGraph extension I used a circular layout which is much faster. But we could provide a more cusotmized version if needed..

Thank you Ralf!
Hello Ralf,
This is a great extension to plot hierarchical data. one thing i am not able to figure out is to replace the "ellipse" with image.
Can you let me know how can i use images instead of "ellipse" as nodes.
Thanks

Hi Phani,
I guess you have to deep dive into the code of the extension and used library to find a solution.

Hi Ralf, it´s a great extension!
I have one Question: I´m using this addon on an own dashboard and I´m having the following issue in runtime:
I guess it can be a compatibility problem... I´ve installed QlikView Personal Edition v11.20.12235.0 SR5 for 64bit running on Windows 7.
Could you tell me which versions of QlikView supports this addon?
Thanks in advance!

Hi Martin,
I cannot say what this issue is related to. The extension itself should work with your QlikView version. Maybe you can upload your QVW file here so I can check if it's related to the data or something else.

Hi Ralf,
Attached the QVW file. It's A POC... I also was thinking that perhaps the issue is related to Internet Explorer version. it can be possible?
thank you very much

I cannot reproduce this issue but had some negative effects with the container object. Please try extension outside of container object..
