Pyramid chart

info

Charts are available with Avalonia Pro.

Pyramid charts are a type of stacked area or bar graph that emphasizes both hierarchy and volume. They are the classic choice for population and sales pipeline visualization.

When to use

• Population pyramids: Showing age and gender distribution in a region.
• Sales pipelines: Visualizing the funnel from leads to closed deals.
• Biological hierarchies: Showing energy flow or species distribution in an ecosystem.

Code example

XAML

<charts:PyramidChart Title="Population Distribution" Height="300"
                       ItemsSource="{Binding PyramidData}"
                       LabelPath="Age" ValuePath="Value"/>

Data model (C#)

public record PyramidItem(string Age, double Value);

public ObservableCollection<PyramidItem> PyramidData { get; } = new()
{
    new("0-14", 15),
    new("15-24", 12),
    new("25-54", 40),
    new("55-64", 18),
