Javascript setting edge class

Anonymous — Thu, 17 Dec 2009 10:56:42 -0000

Hello Jens,

What a beautiful tool is HyperGraph!

I am writing a tool that shows links between words and make use of Javascript to dynamically add nodes and edges. This works very well. However, when I try to set the class of an edge using Javascript, the layout does not change...

I am using the following:

var graphEdge = graph.createEdge(name, sourceNode, targetNode);
attrMgr.setAttribute('class',graphEdge,style);
document.hgApplet.getGraphPanel().getGraphLayout().layout();

The (string) style contains the name of the class that I have in my GraphXML.

Is this the right way, or is there another way to set the class 'runtime'?

Best regards,

Ruben de Graaf

how to i obtain xml data using http

Anonymous — Thu, 07 Feb 2008 17:55:40 -0000

this is what I want to do:

but using a url for the value does not seem to work.

should it work?

is their any fix i could do.

ps: hyper.php returns a xml page, and sends xml headers, and is properly formated. i copyed the output of hyper.php and used it as a file, as hyper.xml. then i open a html file which contained the appropriate applet code. It worked like that.

Center Node

utpal_amin — Thu, 09 Mar 2006 03:39:31 -0000

How can I center a node using Java script. I have
graph in the applet and would like to center a
particular node based on user's click outside of the
graph. I am planning on using javascript. Earlier I
saw an example which was doing that but can't find
that now. It had something like this

document.testApplet.getGraphPanel().centerNode("I20");

Where testApplet is the name of the applet.

Thanks.

edge question

Can you have more than one edge between the same nodes?
If so can you provided some sample xml, thanks This
is a great toolkit!!!

Dynamic

Anonymous — Tue, 05 Jul 2005 20:41:48 -0000

I would like the graph to be dynamic. I would like to use
sql to create the tree on the fly. So say you clicked on
a fourth level leaf, the application would then go out to
the database and requery up the next leafs.

Or can I create the xml file on the fly. The data/tree is
always changing.

Any suggestions?
Is this possible?

newbie features questions/requests

I've just found this hypergraph project, and it looks to
be good for the kind of thing we need. i've played
around with it for a day, and can get it all up and
running with my own xml files.

Our project looks at how risk is propagated through a
tree. The bottom-level nodes (leaves) of the tree show
how individual items contribute to risk. These individual
contributions are combined with their sibling nodes to
pass the combined risk up to the parent node
(branch). Each node has varying degrees of information
about the risk and there may be several hundred nodes
in the entire tree.

Your hypergraph view will be useful for experts to
browse the tree to identify where the influences on risk
reside. We anticipate that using colour coding will make
this reasonably easy to visualise. However, in
order to progress with your applet, we need to be able
to do two other things:

1. as the tree is so large, we'd like to place icons in the
applet which, when clicked, will re-orientate the tree to
pre-specified points (landmarks). The top of the tree is
the obvious one, but others may also be useful e.g. a
commonly used point within the subtree.

2. richer analysis of node information. As stated above,
each node has considerable information about the risk
value associated with it and we would like to control
how it is displayed when a node is double-clicked. At the
moment, the only way I can see this happening
is by opening up another web page, and I'm not even
sure this would work as there would be specific
parameters that must be passed to the page to show
the data. The other thing is, we'd like to show the data
and the hypergraph on the same page to preserve
context - perhaps the graph on the left and a pop-up,
or panel on the right which shows the data for the node
in question. At the moment, our data is stored in the
same xml file as the tree structure, embedded in the
node information. So, our requirement (or wish) is that
double clicking on the node could fire up another applet
(or Flash movie) containing a simple graph of the node
information. Can this be made possible?
