Phasor Plot

Phasor Line Plot

A phasor line plot contains a collection of polar coordinates which are rendered as arrows.

ScottPlot.Plot myPlot = new();

// Start by placing a polar axis system on the plot
var polarAxis = myPlot.Add.PolarAxis(30);
polarAxis.Circles.ForEach(x => x.LinePattern = LinePattern.Dotted);
polarAxis.Spokes.ForEach(x => x.LinePattern = LinePattern.Dotted);

// A Phasor may be added with predefined points
PolarCoordinates[] points1 = [
    new(10, Angle.FromDegrees(15)),
    new(20, Angle.FromDegrees(120)),
    new(30, Angle.FromDegrees(240)),
];
myPlot.Add.Phasor(points1);

// Points on a Phasor may be added or modified after it is created
var phaser2 = myPlot.Add.Phasor();
phaser2.Points.Add(new PolarCoordinates(20, Angle.FromDegrees(35)));
phaser2.Points.Add(new PolarCoordinates(25, Angle.FromDegrees(140)));
phaser2.Points.Add(new PolarCoordinates(20, Angle.FromDegrees(260)));

myPlot.SavePng("demo.png", 400, 300);

Phasor Plot with Labels

Text labels may be applied to individual arrows of a phasor plot.

Phasor.cs

ScottPlot.Plot myPlot = new();

// setup the polar axis
var polarAxis = myPlot.Add.PolarAxis(30);
polarAxis.Circles.ForEach(x => x.LinePattern = LinePattern.Dotted);
polarAxis.Spokes.ForEach(x => x.LinePattern = LinePattern.Dotted);

// create a phasor plot and points in coordinate space
var phaser = myPlot.Add.Phasor();
phaser.Points.Add(new PolarCoordinates(20, Angle.FromDegrees(35)));
phaser.Points.Add(new PolarCoordinates(25, Angle.FromDegrees(140)));
phaser.Points.Add(new PolarCoordinates(20, Angle.FromDegrees(260)));

// add labels for points
phaser.Labels.Add("Alpha");
phaser.Labels.Add("Beta");
phaser.Labels.Add("Gamma");

// style the labels
phaser.LabelStyle.FontSize = 24;
phaser.LabelStyle.ForeColor = Colors.Black;
phaser.LabelStyle.FontName = Fonts.Monospace;
phaser.LabelStyle.Bold = true;

myPlot.SavePng("demo.png", 400, 300);
