3 months ago You're talking about https://tikz.dev/pgfplots/libs-smithchart ?
In that case, this is the wrong location to report the issue. Use https://github.com/pgf-tikz/pgfplots/issues instead.
That having said, check the 2 existing issues https://github.com/pgf-tikz/pgfplots/issues?q=Smith first to see if it isn't already explained.
In the description for the Smith Chart plot, the mirror version of the (more commonly used) impedance chart, to be used as the admittance chart, is described as incorrect . I have been looking into this in some detail, and I cannot see what is so terribly wrong. I have discovered that, in the blank charts that I have on hand, that the increments of the Admittance chart lines (circles) are NOT the same as those on the impedance version. To me this appears to be entirely a matter of breaking-up the pattern so that there are fewer tangential contacts and (perhaps) fewer incremental divisions in areas of the Admittance chart which do not normally need such precision. Other than that, it seems to me that the "mirror version" is essentially correct. Any comments? Am I missing something here?
