Re: [Discuss-gnuradio] Smith Chart in GNU Radio

Hello

Problem solved. I removed the QApplication() from the example. Matplotlib was used for plotting, no need of qApp!!

Thanks

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
