Density plot chart

info

Charts are available with Avalonia Pro.

Density plots smooth a numeric distribution into a continuous curve so peaks and spread are easier to see than in raw point lists.

When to use

• Distribution shape: Inspect concentration, skew, and multiple peaks.
• Smoother histograms: Show the same story as a histogram with a continuous curve.
• Sampling comparisons: Present the overall shape of a dataset without plotting every point.

Code example

XAML

<charts:DensityPlotChart Title="Response time density"
                                   Height="300"
                                   ItemsSource="{Binding DensityData}"
                                   ValuePath="Value" />

Data model (C#)

public record Measurement(double Value);

public ObservableCollection<Measurement> DensityData { get; } = new()
{
    new(12),
    new(15),
    new(18),
    new(19),
    new(24)
};
