Scatter Chart

To render a scatter chart, create an instance of the ScatterSeries, and add it to the Series collection property of SfCartesianChart. The segment size can be defined by using the PointHeight and PointWidth properties.

<chart:SfCartesianChart>

    <chart:SfCartesianChart.XAxes>
        <chart:NumericalAxis />
    </chart:SfCartesianChart.XAxes>

    <chart:SfCartesianChart.YAxes>
        <chart:NumericalAxis />
    </chart:SfCartesianChart.YAxes>  
                
    <chart:SfCartesianChart.Series>
        <chart:ScatterSeries PointHeight="7" 
							 PointWidth="7" 
							 ItemsSource="{Binding Data}" 
							 XBindingPath="XValue" 
							 YBindingPath="YValue"/>
    </chart:SfCartesianChart.Series>

</chart:SfCartesianChart>
SfCartesianChart chart = new SfCartesianChart();
NumericalAxis xAxis = new NumericalAxis();
chart.XAxes.Add(xAxis);
NumericalAxis yAxis = new NumericalAxis();
chart.YAxes.Add(yAxis);

ScatterSeries series = new ScatterSeries()
{
    ItemsSource = new ViewModel().Data,
    XBindingPath = "XValue",
    YBindingPath = "YValue",
    PointHeight = 7,
    PointWidth = 7,
};

chart.Series.Add(series);
this.Content = chart;
