Lollipop chart

info

Charts are available with Avalonia Pro.

Lollipop charts display data points as dots with thin stems extending to the baseline. They are a lightweight alternative to bar charts that reduce visual clutter while maintaining clear value communication.

When to use​

  • Lightweight comparison: When bar charts feel too heavy and you want a cleaner look.
  • Many categories: Reducing ink-to-data ratio when comparing many categories side-by-side.
  • Presentations: Creating visually appealing charts where emphasis is on the data point value.

Code example​

XAML​

<charts:CartesianChart Title="Monthly Sales" Height="250">
    <charts:CartesianChart.HorizontalAxis>
        <charts:CategoryAxis />
    </charts:CartesianChart.HorizontalAxis>
    <charts:CartesianChart.VerticalAxis>
        <charts:NumericalAxis />
    </charts:CartesianChart.VerticalAxis>
    <charts:CartesianChart.Series>
        <charts:LollipopSeries Title="Sales"
                                 ItemsSource="{Binding MonthlySales}"
                                 CategoryPath="Month"
