RE: [corona-dev] Visual representation of a graph.

["Hawkins, Joel" <Joel.Hawkins@xxxxxxxxxxxxx>]

Hi Marcin,

http://www.manageability.org/blog/stuff/open-source-graph-network-visual
ization-in-java/view provides a painfully long list of open source graph
layout packages. Maybe one of them is compatible with Eclipse's license
model. 

I'm assuming GMF doesn't address this issue?

Cheers,
Joel

Subject: [corona-dev] Visual representation of a graph.

I've seen some solution for this in Netbeans Profiler. As you profile an

application you can find hotspots in two ways - one is to go through 
stack trace and find methods that take most time. It is quite natural, 
if there is one inefficient method. This view is shown in
"graph_tree.png".

But, sometimes there are some inefficient methods that are invoked in 
many places. A single invocation it isn't expensive, so you would skip 
it in a drill down view, but in summary it takes a lot of time. If we 
spot such method, we would like to see all traces that lead to it, and 
at least fix the critical path. This view is shown in 
"graph_reverse_tree.png". To get this view, you need to click "show back

trace" in context menu of a method (in any view, eg. hotspots, call 
tree). The selected method becomes a root of the reverse tree.

This defenitely do not provide a full graph structure, but at least 
gives some idea about it. We could consider it.
