### Mapping on group fields (Group layout)

To map on a group, you can use the Group layout, in which you show a summary (such as Last Year's Sales) on change of a geographic field (such as Region). In order to create a map using the Group layout, you must have at least one group and at least one summary field for that group.

###### To map on a group

1. On the `Insert` menu, click `Map`.

   The Map Expert dialog box appears.

2. On the `Data` tab, in the `Layout` area, click `Group`.
3. In the `Placement` area, in the `Place map` list, specify how often your map appears on the report, then click `Header` or `Footer` to specify where to place your map.
4. In the `Data` area, in the `On change of` list, click the group field you want to base your map on, then in the `Show` list, click the summary field you want to display on your map.
5. Click the `Type` tab.
6. Click the map type that best illustrates your data (Ranged, Dot Density, or Graduated). See Map types.
7. In the `Options` area, apply formatting options to your map.
8. Click the Text tab.
9. In the `Map title` field, enter a title for your map.
10. In the `Legend` area, you can click one of the following options:
    - `Full legend` to show a detailed legend on your map
    - `Compact legend` to show a condensed legend on your map
    - `No legend` to exclude the legend from your map.
11. If you click `Full legend`, click `Made by map` to have Seagate Crystal Reports create a legend title based on your map, or click `Specify` to enter your own legend title and subtitle.
12. Click OK.

    Your map is placed in the Header or Footer section of the report, depending on your selection in Step 3.
