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/` -> virtualenv dir  
`/Users/user/Projects/py27_django/` -> project dir

What does it want from me?


Answer: It worked for me in MacOS by installing **graphviz** using `brew install
graphviz` and then testing **dot** by using **dot -v**. You can also download
pkg from here: <http://www.graphviz.org/Download_macos.php>
