Dot plot chart

info

Charts are available with Avalonia Pro.

Dot plot charts display individual data points as simple dots, so values can be compared across categories without the visual weight of bars.

When to use​

  • Value comparison: Comparing individual values across multiple categories without bar clutter.
  • Frequency distribution: Showing how often specific values occur within a dataset.
  • Small datasets: When precise positioning of each data point matters more than aggregate shape.

Code example​

XAML​

<charts:CartesianChart Title="Employee Ratings" Height="250">
    <charts:CartesianChart.HorizontalAxis>
        <charts:CategoryAxis />
    </charts:CartesianChart.HorizontalAxis>
    <charts:CartesianChart.VerticalAxis>
        <charts:NumericalAxis />
    </charts:CartesianChart.VerticalAxis>
    <charts:CartesianChart.Series>
        <charts:DotPlotSeries Title="Ratings"
                                ItemsSource="{Binding RatingData}"
                                CategoryPath="Department"
                                ValuePath="Score"
                                DotSize="12"
                                ShowConnectorLines="True" />
