Population pyramid chart

info

Charts are available with Avalonia Pro.

Population pyramid charts visualize two opposing distributions, most often male and female populations across age groups.

When to use​

  • Demographic analysis: Compare age distribution by sex or region.
  • Segment comparison: Show paired distributions across ordered bands.
  • Planning views: Surface concentration in younger or older cohorts quickly.

Code example​

XAML​

<charts:PopulationPyramidChart Title="Age distribution"
                                 Height="350"
                                 ItemsSource="{Binding PopulationData}"
                                 AgeLabelPath="AgeGroup"
                                 MaleValuePath="Male"
                                 FemaleValuePath="Female" />

Data model (C#)​

public record PopulationBand(string AgeGroup, double Male, double Female);

public ObservableCollection<PopulationBand> PopulationData { get; } = new()
{
    new("0-9", 12, 11),
    new("10-19", 14, 13),
    new("20-29", 16, 17)
};
