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. On the Home page, select a workbook containing a map visualization, click the Actions menu, and then select Open.
2. Drag and drop measure or attribute columns containing map-related data from the Data Panel to the Category (Location) section on the Grammar Panel.
3. Click Layer options in the Category (Location) section of the Grammar pane and click Add Layer to add a new data layer (for example, Layer 2).
   You can also set the layer order, hide the layer, and delete the layer.
4. Drag and drop a column to the Category (Location) 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. Optional: Click Data Layers in the Properties pane. Depending on the layer type, you can select:
   • Name, to change the layer's name.
   • Layer Type, to change the layer type. For example, Polygon.
   • Transparency, to change the visibility of the layer.
   • Outline, to change the layer's outline to Custom to select an Outline Color and set the Outline Width.
   • Size, to change the layer's size in relation to the map.
   • Tooltip, to modify the data that appears on the tooltip when hovering over the layer on the map.
   • Show Layer, to hide or display the layer.
   • Show Legend Title, to hide or display the legend
   • Data Labels Position, to display and select a position for data labels on the map for selected data columns.
6. Click Save.
