Hello Mike, Thanks for your advice. I think this is exactly what I need. I am not sure how to use this option, might you help me?
I use simply the following lines in my code: self.figure.clf() self.axes = self.figure.add_axes([0.1,0.1,0.8,0.8], projection='polar', aspect='equal') and later: self.axes.plot(angle(data),abs(data),label=title,linewidth = 2,zorder=10) Where should I change the resolution feature? With each plot or with figure object? The code is currently open source and available via emGine software (http://www.petr-lorenz.com/emgine/index.php?option=com_content&view=article &id=46&Itemid=56) I am also willing to split smithchart plot as part of matplotlib, this would be great I think.

This is the default in SVN versions of matplotlib, and will be in the next releases. You've clearly done a lot of work on the Smith chart plotting already... It would be great to package that code into something for general use and include in the matplotlib core.
