Apply Multiple Data Layers to a Single Map Visualization

You can use the data layer feature to display multiple data series (different sets of dimensions and metrics) on a single map visualization. The data layers are overlaid on one another in a single map visualization.

  1. Create or open the project where you want to display multiple data layer overlays on a single map visualization. Confirm that you’re working in the Visualize canvas.
  2. Drag and drop a measure or attribute columns containing map-related data from the Data Panel to the Category (Geography) section on the Grammar Panel.

    If you’re creating a map visualization, in the Data Panel, right-click an attribute column and click Pick Visualization then select Map.

  3. Click Layer options in the Category (Geography) section of the Grammar Panel and click Add Layer to add a new data layer (for example, Layer 2).

    Alternatively in the Data Layers tab click Add Layer (+).

  4. Drag and drop a column to the Category (Geography) section. Based on the column values the map visualization automatically updates with a different set of dimensions, and it overlays on the previous layer.
  5. Repeat step 3 and 4 to add multiple data layers on the map visualization.
  6. Click Layer options to use other options such as Order Layer, Hide Layer, and Manage Layers.
  7. In the Data Layers tab of the properties pane, you can specify the options for a layer such as Layer Type, Map Layer, Transparency, and Show Layer.
  8. To refine the data shown for the measure and attribute columns in all the data layers, you can apply a filter such as a Range Filter or List Filter, to the map visualization. For example, you can select a measure or attribute for a layer, then apply filter to reduce the amount of data shown, and add the same measure or attribute to the Color section on the Grammar Panel.
