Wind rose chart

info

Charts are available with Avalonia Pro.

Wind rose charts group values by direction and stack subcategories such as speed bands within each directional sector.

When to use​

  • Meteorology: Show wind frequency by direction and speed band.
  • Directional events: Compare traffic, movement, or signal occurrences around a compass.
  • Operational analysis: Summarize heading-based activity in one compact polar chart.

Code example​

XAML​

<charts:WindRoseChart Title="Wind distribution"
                                Height="320"
                                ItemsSource="{Binding WindData}"
                                DirectionPath="Direction"
                                SpeedPath="SpeedBand"
                                ValuePath="Frequency" />

Data model (C#)​

public record WindSample(string Direction, string SpeedBand, double Frequency);

public ObservableCollection<WindSample> WindData { get; } = new()
{
    new("N", "0-10", 12),
    new("N", "10-20", 6),
    new("NE", "0-10", 8)
};
