This Library allows the fully automatic generation of Smith Charts with various customizable parameters and well selected default values. The Smith chart may also be used for lumped-element matching and analysis problems. The generated plots blend seamless into matplotlib's style and support almost the full range of customization options. The 3D Smith Chart appears as a crystal ball for looking into resistance, reactance, capacitance, inductance, impedance, etc. PySmithPlot is a matplotlib extension providing a projection class for creating high quality Smith Charts with Python. special handling of other matplotlib.patch objects like arrows.There are still some plans for the future and they hopefully don't take another two years: fixed issues with axis label display and placement.renamed some parameters to improve consistency.changed behaviour for normalization and placement of the label.changed handling of input data and renormalization now the actual datatype (S,Z,Y-Parameter) can be specified when calling plot().plot() can now interpolate lines between points or generate an equidistant spacing.plot() now also handles also single numbers and purely real data.Additionally since 2019 it includes frequency visualization too within the 3D space-spotting the clockwise and counter clockwise dependencies as frequency sweeps in real-time.After 2 years of getting dusty pySmithPlot now got some new features and bug fixes. (North pole: perfect match, South pole infinite mismatch). The South-represents active areas with negative resistance, North areas represent passive with positive resistance, East inductive and West capacitive. The 3D Smith chart tool extends the Smith chart capabilities for the first time since the 1939s to make it usable for circuits with negative resistance based on a unit sphere that plots circuits with reflection coefficient magnitudes larger than one by mapping them as arcs on the 3D sphere. The simultaneous display of a variety of parameters form imported touchstone files speeds up the analysis phase and helps in the optimizations of the high frequency devices. The tool also has an advanced analysis mode for S-parameters, stability circles, power levels, group delays and quality factors making it a new software for the measuring stage or design stage of microwave devices. The 3D Smith chart is an ideal educational tool for the fast and simple understanding and matching use of both 2D and 3D Smith charts in both Z/Y configurations when using resistances, capacitors, inductors, in series or shunt configuration, transmission lines or stubs. The 3D Smith chart tool, that enables the understanding and use of both 2D Smith chart and 3D Smith chart, is now available for free for all undergraduate, master and PhD students.
