Defining the map points for the map layer

On the Points Definition tab for the map layer, you select the geocode attribute to use for the map points, and whether the map layer uses aggregated points.

1. From the Geospatial attribute list, select the geocode attribute to use for the map locations.
   
2. You also select whether the map locations need to be aggregated.
   • To not aggregate the map locations, click Detail points.
   • To aggregate the map locations, click Aggregated points.

   For example, if the view contains a simple list of stores, with the geocode being the store location, you would not need to aggregate the locations, and could use the detail points option.

   But if the view contains a list of sales transactions, with the geocode being the store location for the sale, then to generate a single list of store locations, you might aggregate by a dimension such as the store name.

3. If you are creating an aggregated map layer, then you configure the list of grouping dimensions to use for the aggregation.
   1. To add a dimension to the list, drag a dimension from the Available attributes list to the Grouping dimensions list.
      
   2. To determine the order for applying aggregation, drag each dimension to the appropriate location in the list. The dimension at the top of the list is applied first.
   3. To remove a dimension from the list, click its delete icon.
4. For a heat map layer, you can select a metric to use for setting the layer point and heat cloud colors.

   For example, if the locations are stores, then the heat map layer colors could reflect the total sales at each store.

   If you do not select a metric, then the heat map colors are based on the relative density of the points on the map. So if the locations are stores, then the heat map colors would change based on the number of stores in a given area.

   To select the metric, click Select Metric. On the metric dialog, click the metric, then click Apply.

   
   
   

   For predefined metrics or system metrics, the aggregation method is built in.

   For other attributes, the default aggregation method is assigned. You can then use the list to select a different aggregation method.

   To select a different metric, click the delete icon, then click Select Metric.
