recursive systemd dependencies graph

Hello
I wonder if there is any way to plot full dependencies graph for service.
  All examples I've seen (for systemd-analyze and systemctl list-depencensies)   show only one level of dependencies.
For example if my service A  requires service B and  service B requires service C  I would like to get picture like this  A -> B -> C.     But seems that it works only for target dependencies.

Best regards,
Max

Re: recursive systemd dependencies graph

Thanks for the answer!
I am afraid it is not exactly what I am looking for.  I want something more systemd specific.  I've written my application and wrapped it into systemd services  and I would like to get graph with dependencies.  Unfortunately arch packages is not an option because we probably won't use Arch in production. ( Although I, personally, am a big fan of this distributive. )
I was hoping that somebody with experience in systemd may have answer.

That is also in the man page for systemd-analyze. And the systemctl man page mentions an --all option for the list-dependencies command that might be of interest to the OP.

Thanks Raynman!

It's a shame that I missed option --all.  ^(   It's even more detailed that i need to but I can deal with it.  Thanks !

And I don't get how to achieve the same with systemd-analyze. It works very well if I need to get graph for all services, but if I try to get only graph for particular service and his children I get only two level's graph.
