Ternary chart

info

Charts are available with Avalonia Pro.

Ternary charts visualize three-component mixtures where each point represents the relative contribution of A, B, and C.

When to use​

  • Mixture analysis: Show composition of blends, materials, or resource allocation.
  • Three-way balance: Compare proportions that always sum to a whole.
  • Scientific classification: Place samples within a triangular decision space.

Code example​

XAML​

<charts:TernaryChart Title="Mixture composition"
                               Height="320"
                               ItemsSource="{Binding TernaryData}"
                               APath="Sand"
                               BPath="Silt"
                               CPath="Clay"
                               ALabel="Sand"
                               BLabel="Silt"
                               CLabel="Clay" />

Data model (C#)​

public record TernaryPoint(double Sand, double Silt, double Clay);

public ObservableCollection<TernaryPoint> TernaryData { get; } = new()
{
    new(60, 25, 15),
    new(35, 45, 20),
    new(20, 30, 50)
};
