Hi I am trying to figure out how to use smith chart as a sink in GNU Radio. I made an OOT (https://github.com/mitul93/gr-smithchart) using pyQT by following Tim O'shea's work. It is merely a skeleton, still lots of work to do.
I made two versions of smith chart - one using pyQT and another using matplotlib (ploar plot). After executing example_smithsink_numpy.py when I close the graph, the program won't stop. I tried to write an close_event() for the graph, but it didn't work. Is it happening due to the fact I am using it with GNU Radio? To display data point on graph, shall I use message passing or simple vector input? Also please give me your feedback about expected function that I must implement in smith chart. Thanks Mitul Vekariya Institute of Technology Nirma University
