Apply Multiple Data Layers to a Single Map Visualization
You can add data layers that provide details about dimensions and metrics to a map visualization. Data layers overlay the base map visualization.
- On the Home page, select a workbook containing a map visualization, click Actions, and then select Open.
- Drag and drop measure or attribute columns containing map-related data from the Data Panel to the Category (Location) section on the Grammar Panel.
- 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).
- 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.
- Optional: Click Data Layers in the Properties pane. Depending on the layer type, you can select:
- Name - Change the layer name.
- Layer Type - Change the layer type. For example, Polygon.
- Transparency - Change the visibility of the layer.
- Outline - Change the layer outline to Custom to select an Outline Color and set the Outline Width.
- Size - Change the size of the layer in relation to the map.
- Tooltip - Modify the data that appears on the tooltip when hovering over the layer on the map.
- Show Layer - Display or hide the layer.
- Show Legend Title - Display or hide the legend.
- Data Labels Position - Display and select a position for data labels on the map for selected data columns.
- Auto Zoom - Automatically zoom to this layer's extent whenever the map visualization renders.
- Enable Selection - Enable selection of data for this layer using the Rectangle, Radial, or Polygon selection toggles, or using left or right mouse click.
- Click Save.
