get .dot file as output

[namndh]

I have followed the instructions from this link and got a very nice image that shows the flow of my code as expected but I would like to get .dot file for further purpose. I have tried to change graphviz.output_file = 'flow.png' to graphviz.output_file = 'data_frame.dot' and tried to run the command line pycallgraph graphviz -l dot -- mycode.py but I do not have the .dot file as output file. How can I solve this problem?

How did you get this to work. I've gotten the program to run to the end without an error but I cannot find where the output is located.
