hey everyone!
so i was wondering if anyone could help with this:
i've built a visualisation of an intial graph already, and then i put an eventlistener on one of the nodes such that when u click it, a new graph will be shown.
what i want then is to add an edge between the root of this new graph and the node that triggered this!
any help will be greatly appreciated ! (also note that my code is inspired by the codes posted in this forum !!
)
thank you very much!
best!

Good morning Yaszine,
thanks for sharing your source code here in the forum. One question ahead, your two data sets have different schema which makes the "merging" of both graphs more complicated as far as I see. Apart from that it looks like you always create a new visualization object when a node is clicked. As you said you want to add the new data to the existing visualization, so the basic idea I would have is to add the new data always to the very first data set you created and use only one visualization object. At least this is what I do here
http://goosebumps4all.net/34all/bb/showt...hp?tid=153
and it works fine in that case. So maybe you could clarify if you really need to merge to graphs with different schemas and hopefully somebody around can help you further.
cheers

hey !
thanks for ur reply ! it helped a lot !
well i've tried what you told me, but it still doesn't work !
can u please have a look at it once again ! ? when clicking the last node of my initial tree, we should be able to see an adge between this last one and the root of the next tree (graph).
why isn't this happening ?!
why ?!
thank you very much again,
have a nice day!
yassine!
Good morning Yaszine,
can't see it myself right now, sorry, hope somebody else can help you further
cheers

hey ! so i solved the problem !
thank you anyways !
cheers !
Yassine
congrats!
could you share the solution source code with us?
thanks
martin
here is the code !!
i simply made it explicit to redo the visualisation for the nodes that were just added ! and i added an edge between the node that triggered this and the root node of the new tree!
anyways ! have a look at the code! it's not so complicated !
cheers!
yassine
great, thanks for sharing, works perfectly
Hi yassine,
thanks for sharing, i just made a few tests with your code. I m also at a point where i'd like to add new data to my graph, maybe i can manage it the same way like you just did it. As far as I can see, you are not using the GraphMLConverter directly like me, you are doing it with "new DataSource("data.xml", graphml");" Is there any advantage to the way i m using it right now? (
link to my post at flare forum,
SourceCode here)
just tried to change your source from fisheye to radialtree and some strange stuff is happening now, the graph becomes crazy when you click throw the new nodes and they'll be add static and not flowing around, maybe you can see what i messed up.. I just added/changed this code:
Code:
var lay:RadialTreeLayout = new RadialTreeLayout();
lay.useNodeSize = false;
_gdf = new GraphDistanceFilter([root], 2,NodeSprite.TREE_LINKS);
vis.operators.add(_gdf);
vis.operators.add(lay);
my test in action, =>

Hi Dennis
you have set
Code:
vis.continuousUpdates = true;
which is not a good idea if you are using the RadialTreeLayout. A quick hack solution should be something like
Code:
loader.addEventListener(Event.COMPLETE, function(evt:Event):void
{
var ds1:DataSet = loader.data as DataSet;
var dt:Data = Data.fromDataSet(ds1);
add(dt);
data.addEdgeFor(n,data.nodes[i]);
setupNodes(i,data.nodes.size);
i = data.nodes.size;
_gdf.operate(); // new
updateRoot(n); // new
});
Calling _gdf.operate() before updating the root is to set the visibility of the new nodes without any transition.
cheers
