Beeswarm plot chart

info

Charts are available with Avalonia Pro.

Beeswarm plots arrange points within each category to avoid overlap while preserving the distribution of individual observations.

When to use

• Raw observation display: Show every point instead of only summary statistics.
• Category comparison: Compare spread and clustering across groups.
• Distribution detail: Reveal dense stacks that a plain scatter plot would hide.

Code example

XAML

<charts:BeeswarmPlotChart Title="Test scores by group"
                                    Height="300"
                                    ItemsSource="{Binding BeeswarmData}"
                                    CategoryPath="Category"
                                    ValuePath="Value" />

Data model (C#)

public record BeeswarmPoint(string Category, double Value);

{
    new("A", 62),
    new("A", 65),
    new("B", 74),
    new("B", 79)
};
