# How to preserve graph properties under subgraph in MMA9 [duplicate]

Possible Duplicate:
Preserving labels when using graph functions

I'm using

g = SocialMediaData["Twitter", "FriendNetwork"]


to get a nice graph with tooltips for the vertices, etc. Next, I get the weakly connected components via

wcc = WeaklyConnectedComponents[g]


and then I do

sg = Subgraph[g, wcc[[1]]]


to get the largest component. But, all the properties are gone in sg, i.e. I no longer have the tooltips, etc.

Any suggestions?

You can format your code by starting it with 4 spaces or selecting the text and hitting CTRL+K. See my edit in your question. –  István Zachar Dec 5 '12 at 20:48
