Common Patterns

Pattern 1: Choropleth Map with Data Binding

Use Case: Visualize statistical data across regions with color-coded shapes.

@{
    var colorMapping = new List<MapsColorMapping> {
        new MapsColorMapping { Value = "Low", Color = "#90EE90" },
        new MapsColorMapping { Value = "Medium", Color = "#FFD700" },
        new MapsColorMapping { Value = "High", Color = "#FF6347" }
    };
}

<e-maps-layer shapeData="@geoJsonData" 
              dataSource="@statisticsData"
              shapeDataPath="RegionName" 
              shapePropertyPath="@(new[] { "name" })">
    <e-layersettings-shapesettings 
        colorValuePath="DataLevel"
        colorMapping="colorMapping">
    </e-layersettings-shapesettings>
</e-maps-layer>

Pattern 2: Interactive Map with Zoom and Selection

Use Case: Enable user interaction for detailed exploration.

<ejs-maps id="maps">
    <e-maps-zoomsettings 
        enable="true" 
        enableSelectionZooming="true"
        toolbars='new string[] {"Zoom", "ZoomIn", "ZoomOut", "Pan", "Reset"}'>
    </e-maps-zoomsettings>
    
    <e-maps-layers>
        <e-maps-layer shapeData="@mapData">
            <e-layersettings-selectionsettings 
                enable="true" 
                fill="#8B0000"
                opacity="0.5">
            </e-layersettings-selectionsettings>
            
            <e-layersettings-highlightsettings 
                enable="true" 
                fill="#FF6347">
            </e-layersettings-highlightsettings>
        </e-maps-layer>
    </e-maps-layers>
</ejs-maps>

Pattern 3: Multiple Data Layers

Use Case: Overlay multiple data sets on a single map.

<e-maps-layers>
    <!-- Base layer: Country boundaries -->
    <e-maps-layer shapeData="@countryData" type="Layer">
        <e-layersettings-shapesettings fill="#E5E5E5"></e-layersettings-shapesettings>
    </e-maps-layer>
    
    <!-- Sublayer: State boundaries -->
    <e-maps-layer shapeData="@stateData" type="SubLayer">
        <e-layersettings-shapesettings fill="transparent" border-width="1"></e-layersettings-shapesettings>
    </e-maps-layer>
    
    <!-- Data layer: Markers -->
    <e-maps-layer type="Layer">
        <e-layersettings-markersettings>
            <e-layersettings-markersetting dataSource="@locations" shape="Circle"></e-layersettings-markersetting>
        </e-layersettings-markersettings>
    </e-maps-layer>
</e-maps-layers>

Pattern 4: Bing Maps Integration

Use Case: Use Bing Maps as base layer with custom data overlay.

<ejs-maps id="maps">
    <e-maps-layers>
        <!-- Bing Maps base layer -->
        <e-maps-layer layerType="Bing" bingMapType="Aerial" key="YOUR_BING_MAPS_KEY">
