Radar Plot

Radar Plot Quickstart

A radar chart can be created from a single array of values.

ScottPlot.Plot myPlot = new();

double[] values = { 78, 83, 84, 76, 43 };
myPlot.Add.Radar(values);

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

Radar Plot with Multiple Series

A single radar chart can be used to display values from multiple series using a 2D array

Radar.cs

ScottPlot.Plot myPlot = new();

double[,] values = {
    { 78,  83, 84, 76, 43 },
    { 100, 50, 70, 60, 90 }
};

myPlot.Add.Radar(values);

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

Radar Legend

Collections of radar values (radar series) can be labeled so they appear in the legend

Radar.cs

ScottPlot.Plot myPlot = new();

double[,] values = {
    { 78,  83, 84, 76, 43 },
    { 100, 50, 70, 60, 90 }
};

var radar = myPlot.Add.Radar(values);
radar.Series[0].LegendText = "Sebastian";
radar.Series[1].LegendText = "Fernando";

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

Radar Series Customization

Radar plots have a collection of RadarSeries objects which each describe a set of values and the styling information used to display it as a shape on the radar plot. Users may change properties of radar series objects to achieve a high level of customization over each shape.

Radar.cs

ScottPlot.Plot myPlot = new();

double[,] values = {
    { 78,  83, 84, 76, 43 },
    { 100, 50, 70, 60, 90 }
};

var radar = myPlot.Add.Radar(values);

radar.Series[0].FillColor = Colors.Transparent;
radar.Series[0].LineColor = Colors.Blue;
radar.Series[0].LineWidth = 3;
radar.Series[0].LinePattern = LinePattern.DenselyDashed;

radar.Series[1].FillColor = Colors.Green.WithAlpha(.2);
radar.Series[1].LineColor = Colors.Green;
radar.Series[1].LineWidth = 2;

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

Radar Spoke Labels

Labels can be assigned to spokes to label values around the circumference of the radar plot

Radar.cs

ScottPlot.Plot myPlot = new();

double[,] values = {
    { 78,  83, 84, 76, 43 },
    { 100, 50, 70, 60, 90 }
};

var radar = myPlot.Add.Radar(values);
radar.Series[0].LegendText = "A";
radar.Series[1].LegendText = "B";

string[] spokeLabels = { "Wins", "Poles", "Podiums", "Points", "DNFs" };
radar.PolarAxis.SetSpokes(spokeLabels, length: 110);

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

Radar Radial Tick Labels

Radar radial tick positions and labels may be defined by the user

Radar.cs

ScottPlot.Plot myPlot = new();

double[,] values = {
    { 78,  83, 84, 76, 43 },
    { 100, 50, 70, 60, 90 }
};

var radar = myPlot.Add.Radar(values);

double[] tickPositions = { 25, 50, 75, 100 };
string[] tickLabels = tickPositions.Select(x => x.ToString()).ToArray();
radar.PolarAxis.SetCircles(tickPositions, tickLabels);

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

Radar with Straight Lines

Radial ticks may be rendered using straight lines instead of circles

Radar.cs

ScottPlot.Plot myPlot = new();

double[] values = { 78, 83, 100, 76, 43 };
var radar = myPlot.Add.Radar(values);
radar.PolarAxis.StraightLines = true;

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

Axis on Top of Data

Radar charts can be customized so the axis is rendered on top of the data

Radar.cs

ScottPlot.Plot myPlot = new();

double[] values = { 78, 83, 100, 76, 43 };
var radar = myPlot.Add.Radar(values);

// make the shape opaque
radar.Series[0].FillColor = Colors.RebeccaPurple;

// render the axis above the data
radar.IsAxisAboveData = true;

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