You can use a file sink to write the samples out to a file, and write some program to process the file.

Or, you need to create your own block in c++ or python. If c++, the "how to write a block example" is a good reference. If python, the wxgui sinks are a good reference (see gr.message_sink and gr.msg_queues to get data out of the stream and into python).

Thanks, but i dont want to use GUI sink. I want to get an array of samples 
which represent the periodogram. So that i can do further processing on them.

You should probably start by looking at the existing wx gui sinks, copy and 
modify one: http://gnuradio.org/trac/browser/gnuradio/trunk/gr-wxgui/src/python

The vector sink is not what you want here.
