Why doesn't git branch --graph show branching local branches?

Question

git

I created a test repository,
created several branches, created two branches from the master, from them one more from each. Made several commits in each of them. And I want to see a graph showing which branch went from which I write . I
git branch --graph
get

[email protected]:~/projects/test$ git branch
another
is16
* master
one
sub16
[email protected]:~/projects/test$ git log --graph

Why is that ?

Answer 1

Maybe
?
git branch does not have a --graph option.
