Hi Robert,

I'm sending this reply to the Mercurial mailinglist too. This is where
normal user questions should go -- unless you're interested in paid

I'm afraid I don't know of a tool that can do this out of the box. The
same thing was asked here today:

There's no answers yet.

Another option is to write the tool yourself :) There are Mercurial
bindings for Python, Java, and Scala:

That's fine, but please use the mailinglist. That way your mail is
filtered correctly at my end and you'll likely get faster feedback since
more people see the question.

While TortoiseHg can draw nice graphs based on revision sets, it wont
connect changesets unless they are parent-child. So even if you can pick
out the right branch and merge points, you wont get a nice graph
connecting these points. You will just get a list of revisions with
unconnected dots.

As for finding the branch points, then I think this should help:

  hg log -r "parents(branch(B)) and not branch(B))"

It finds changesets outside the branch, but with a child on the branch.
They denote points in the graph where the branch started or where other
branches were merged into it.
