Data Binding for Combined Maps

The Combined Map allows you to overlay multiple map layers in a single visualization. You can add a new layer by selecting the “+” icon next to Map Layers. Available layer types include:

• Area Layer

• Bubble Layer

• Heat Layer

• Symbol Layer

• Flow Line Layer

• Path Layer (unique to Combined Map; not available as a standalone map type)

Each layer has its own Data Binding slots, which work the same as their individual map counterparts. You can configure, reorder, and remove layers at any time using the ellipsis (…) menu next to the layer name.

Path Layer Data Binding

The Path Layer is specific to the Combined Map and is used to draw routes or paths across a map. It includes the following binding slots:

• Path Name – Assigns a name or identifier to each path, allowing multiple paths to be displayed and distinguished.

• Path – Defines the path coordinates. Typically, this is a sequence of latitude/longitude pairs that determine the route’s shape.

• Color – Sets the color of each path. You can bind a field to dynamically color paths by category or measure.

• Width – Controls the thickness of each path line. You can bind a numeric field to vary line width according to data values.

• Tooltip – Displays additional information when hovering over a path (e.g., route details, metrics, categories).

Managing Layers

• You can add an unlimited number of layers to a Combined Map.

• Use the ellipsis (…) menu beside a layer to configure or remove it.

• Layers can be stacked to display different types of geospatial data together (e.g., showing flow lines on top of regions, or paths alongside heatmaps).

The following map has been created using this native query dataset froom the AdventureWorks Data Warehouse:

-- Combined Map Query: Region (Area Layer) + City (Bubble Layer)
SELECT
    st.SalesTerritoryCountry AS Country,
    st.SalesTerritoryRegion AS Region,
    g.City AS City,
    g.StateProvinceName AS StateProvince,
    g.EnglishCountryRegionName AS CountryName,
    SUM(fis.SalesAmount) AS TotalSales
FROM dbo.FactInternetSales fis
INNER JOIN dbo.DimSalesTerritory st
    ON fis.SalesTerritoryKey = st.SalesTerritoryKey
INNER JOIN dbo.DimCustomer c
    ON fis.CustomerKey = c.CustomerKey
INNER JOIN dbo.DimGeography g
    ON c.GeographyKey = g.GeographyKey
GROUP BY
    st.SalesTerritoryCountry,
    st.SalesTerritoryRegion,
    g.City,
    g.StateProvinceName,
    g.EnglishCountryRegionName
ORDER BY
    TotalSales DESC;
