RSmithChart class

public sealed class RSmithChart : Control

The interactive Smith chart.

Constructors

RSmithChart()

The empty chart, with the impedance grid.

Properties

double Z0 { get; set; }

The normalization impedance, ohm (50).

bool ShowImpedance { get; set; }

Whether the impedance grid is drawn (true).

bool ShowAdmittance { get; set; }

Whether the admittance grid is drawn (false).

double MaxGamma { get; set; }

The largest |Γ| shown: 1 is the normal chart, 2 or more the expanded chart, where the resistance is negative outside |Γ| = 1.

List<RComplexSeries> Series { get; }

The curves (one Γ per frequency).

List<RSmithMarker> Markers { get; }

The points.

List<RSmithCircle> Circles { get; }

The circles (VSWR, Q, stability, gain, noise).

bool MarkerValues { get; set; }

Whether each marker writes Z and VSWR under its label (true).

bool ShowReading { get; set; }

Whether the reading under the pointer is written (true).

double Zoom { get; }

The magnification of the view (1: the whole chart).

Complex ViewCenter { get; }

The Γ at the center of the view (0 for the whole chart).

CultureInfo Culture { get; set; }

How the numbers are written (invariant: the point).

string BackgroundKey { get; set; }

The theme resource of the background.

string GridKey { get; set; }

The theme resource of the grid.

string InkKey { get; set; }

The theme resource of the texts and of the outer circle.

double TextSize { get; set; }

The size of the texts.

Complex? Under { get; }

The Γ under the pointer, or null.

double Radius { get; }

The radius of the circle |Γ| = 1 in pixels, with the zoom.

Methods

Point PixelOf(Complex gamma)

The point of the control of a reflection coefficient.

Complex GammaAt(Point p)

The reflection coefficient of a point of the control.

void ZoomAt(Point p, double factor)

Zooms by a factor keeping the Γ at the given point where it is (the wheel does it at the pointer); the zoom stays from 1 to 50.

void ResetView()

Shows the whole chart again.

void SavePng(string path, double widthCm = 12, double dpi = 300)

Saves the chart as PNG, square, the given centimetres wide at the given dpi (RImage); the chart is then laid out again on the screen.

void Render(DrawingContext ctx)

Draws background, grids, circles, curves, markers, legend and reading.

void Move(RSmithMarker m, Complex gamma)

Brings a marker to the given Γ (inside |Γ| = MaxGamma) and tells MarkerMoved: what the mouse does, usable from code and tests.

Events

event Action<RSmithMarker> MarkerMoved

A draggable marker has been moved.
