Using Layer Maps

Use layer maps to visualize data with custom geographic boundaries. To create layer maps, you upload GeoJSON files that shape layers over a base map and join with data to visualize associated metrics and dimensions. You can customize the color, border, and opacity of the shape layers.

    1. From the Shape file key field list, select the field that you want the shape to visualize from the fields available in the uploaded shape file.
    2. From the Dataset key field list, select the dataset field that you want the shape to visualize.
    3. To assign color to the shapes, select a field under Color.
      If the color field is a measure, the shape uses gradient coloring. If the color field is a dimension, the shape uses categorical coloring. If a color field is not assigned to the shape, you can use the fill color option in the Styling section to set a common color for all shapes.
  11. Under Styling, set the fill color and opacity and the border color, thickness, and opacity.
    If you did not assign a color field to the shape, you can use the fill color option to set a common color for all shapes.

    2. Under Map options, select the type of the base map that appears beneath the data.
      For example, you can use a gray canvas, a street view, or a satellite view.
    3. To enable panning and zooming for the map, enable the Allow panning and zooming option.
    4. Under Map layers, click Open menu icon, the Open menu icon, next to a map layer and select Edit to update the layer settings.
