python - pycallgraph with pycharm does not work

Question

I'm using mac os x and trying to setup pycallgraph.
Ive installed pycallgraph with pip and graphviz with homebrew.
Everything works from shell. But not from pycharm.

from pycallgraph import PyCallGraph
from pycallgraph import Config
from pycallgraph import GlobbingFilter
from pycallgraph.output import GraphvizOutput


config = Config()
config.trace_filter = GlobbingFilter(exclude=[
     'pycallgraph.*',
])

graphviz = GraphvizOutput(output_file='filter_exclude.png')

with PyCallGraph(output=graphviz, config=config):
    def my_fun(): 
        print "HELLO"
    my_fun()

/Users/user/Projects/py27/bin/python /Users/user/Projects/py27_django/test2.py
Traceback (most recent call last):
  File "/Users/user/Projects/py27_django/test2.py", line 15, in <module>
    with PyCallGraph(output=graphviz, config=config):

    self.reset()
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/pycallgraph.py", line 53, in reset
    self.prepare_output(output)
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/pycallgraph.py", line 97, in prepare_output
    output.sanity_check()
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/output/graphviz.py", line 63, in sanity_check
    self.ensure_binary(self.tool)
  File "/Users/user/Projects/py27/lib/python2.7/site-packages/pycallgraph/output/output.py", line 96, in ensure_binary
    'The command "{}" is required to be in your path.'.format(cmd))
pycallgraph.exceptions.PyCallGraphException: The command "dot" is required to be in your path.

Process finished with exit code 1

Here:
/Users/user/Projects/py27/ -> virtualenv dir
/Users/user/Projects/py27_django/ -> project dir

What does it want from me?

It wants the dot command (from graphviz) to be in your path. If you start a terminal and do which dot, does it find the dot binary you installed with homebrew? — Lukas Graf
Chances are you're running into this issue: PyCharm - $PATH on OS X — Lukas Graf
@LukasGraf yes, of course: it is /usr/local/bin/dot. Everything works fine from shell, as I said. It is clear, that I must add this path somewhere, but where?? — akaRem
See the question I linked and the answers to it: homebrew links packages to /usr/local/bin, which isn't in the default $PATH. Your .bash_profile probably adds it to $PATH, but that only applies to terminals. Append /usr/local/bin/ to your $PATH in your PyCharm configuration as described in this answer, and you should be fine. — Lukas Graf
@LukasGraf Thank you for mentioning graphviz. Boy, I had trouble figuring out where dot comes from — Antony

Install graphviz in MacOS by using:

brew install graphviz

or in Ubuntu by using:

sudo apt-get install graphviz

Then you can test dot by using:

dot -v

You can also download pkg from here
