The Complex Graphics routines in the Presentations Application contain routines that make it quite easy to draw Smith Charts and plot impedence curves on them. I have posted an example at Peter Lindsay's web site at the Mathematics department at St. Andrews University. It should appear within a few days. It has a Mathematica notebook and a PDF file. http://www.st-andrews.ac.uk/~pl10/c/djmpark/ David Park djmpark at comcast.net http://home.comcast.net/~djmpark/index.html From: David Kirkby [mailto:drkirkby at gmail.com] I'm looking to plot data colected via an experiement on a Smith Chart. Does anyone have code for one, which will save me the not-inconserable effort of writing one? There is one in the Wolfram archive http://library.wolfram.com/infocenter/Demos/441/ but that is written for a very old version of Mathematica, and it appears unable to plot experimental data. There is also a Smith Chart on the Wolfram Demonstrations project http://demonstrations.wolfram.com/TheSmithChart/ but that one has a serious flaw. If one puts R=50 Ohms, C=0, L=0, then the point should be in the middle of the Smith chart, not to the far right hand side. It must be the most obvious point to plot on a Smith chart, but it fails.
