Error with Hypergraph and some data in Chinese
Hi Rob, A nice extension, but I have a problem with the extension. When I use Graph as Hypergraph with some data in Chinese. It returns an error content of Hypergraph. You can see it in the following image.

Could you give me a hand--Roc michael 17:11, 2 May 2009 (UTC)


 * Fix the encoding.

SemanticGraph/include/SemanticGraphSetting.php

'preamble' => ... encoding = "iso-8859-1"?> //before

'preamble' => ... encoding = "utf-8"?> //after


 * Fix the font-name.


 * Make property file.

e.g.) image/hypergraph/hexplorer.prop

hypergraph.hyperbolic.text.fontName=Sim Sun


 * Add line

SemanticGraph/include/SemanticGraphFiles.php

$output .= '';

How is the integration into Semantic Result Formats
Is this extension still maintained and if yes how is the integration with Extension:Semantic Result Formats planned?--MWJames 12:26, 25 September 2010 (UTC)

Colour setting of incoming, outgoing relations and for different property types ...
Hi,

Is it somehow possible to allow some parameters to set the colour of incoming vs. outgoing relations and if more than one property type is displayed to allow to set different colour so that connections can be divided easily. --MWJames 18:21, 26 June 2011 (UTC)

Problems in cases the page title contains comma
We encountered problems in cases where the page title contains a comma, Semantic Graph would show an error message no valid pages found for option resource while renaming the same page without a comma would display the hypergraph. --MWJames 13:32, 29 June 2011 (UTC)

 * Is their a chance you are running SMW 1.6+ because if so Semantic Graph is just not up for it, only works prior 1.6. Maybe next time you could add some information about what SMW version etc. you are using, it is hard for anyone to give advice with no related context while looking at an error log.

 * Quick fix. In SemanticGraphQuery.php change getPagesFromSemantics function:
