    Code-Behind:

    using System.Windows;
    using DevExpress.Xpf.Map;
    namespace HeatmapPointStorage {
        public partial class MainWindow : Window {
            public MainWindow() {
                InitializeComponent();
                storage.Points.Add(new HeatmapPoint(new GeoPoint(23.5309, -0.4211), 1));
                storage.Points.Add(new HeatmapPoint(new GeoPoint(32.3248, 21.0537), 0.5));
                storage.Points.Add(new HeatmapPoint(new GeoPoint(14.1503, 16.3626), 1));
                storage.Points.Add(new HeatmapPoint(new GeoPoint(7.2144, 34.2711), 1));
                storage.Points.Add(new HeatmapPoint(new GeoPoint(-4.5456, 10.1143), 0.5));
            }
        }
    }
    

    You can also create heatmap points in XAML:

    <dxm:HeatmapProvider.PointSource>
        <dxm:HeatmapPointStorage>
            <dxm:HeatmapPointStorage.Points>
                <dxm:HeatmapPoint Value="0.5">
                    <dxm:HeatmapPoint.Location>
                        <dxm:GeoPoint Latitude="32.3248" Longitude="21.0537"/>
                    </dxm:HeatmapPoint.Location>
                </dxm:HeatmapPoint>
                <!-- Other heatmap points. -->
            </dxm:HeatmapPointStorage.Points>
        </dxm:HeatmapPointStorage>
    </dxm:HeatmapProvider.PointSource>
