6.6.5 Binding a Chart to Geographical Data (Map)
You can bind a chart to a datasource containing geographical data to create a map chart. A map chart displays summarized data grouped by physical location in the form of a geographical map. It has many of the same properties of other chart types, but also differs in some ways. The following sections explain how to create and modify map charts.
To create a map chart, first add a chart element to the report. (See Adding a Chart Element for more details.) Then follow the steps below to bind the chart to a data source:
1. Click on the chart to select it. This opens the Data panel and Binding panel.
2. In the Binding panel, click 'Select Chart Style', and choose the 'Map' chart type.

3. Click the 'Apply' button (or double-click the 'Map' icon). The Binding panel changes to display a 'Geographic' field.
If your columns contain longitude and latitude data (in decimal format) rather than location names, use the X (Longitude) and Y (Latitude) fields of the Binding panel.
4. From the Data panel, drag a geographic dimension onto the 'Geographic' field in the Binding panel.
5. To change the default map settings (default map is 'World', and default level is 'City'), click the red “?” button to open the geographic level editor.

The map that you select for a geographic field applies to all other geographical fields.
6. In the level editor, select the desired region from the 'Map' menu: Asia, Canada, Europe, Mexico, U.S., or World.
7. From the 'Layer' menu, select the geographical layer that corresponds to the data in the selected field.
This specifies the layer of the geographical database against which field values should be matched (e.g., city names should be matched against the city layer, etc.). The options available in the 'Layer' menu depend on the previously selected 'Map' option.
8. From the 'Mapping' menu, select the desired mapping definition. The options will include “Built-in” and any custom mappings.
The Chart Editor attempts to resolve values in the selected geographic field against the corresponding layer in the map database. If all data values are successfully matched, a green check mark is displayed. If some data values cannot be matched, a red “?” is displayed.

9. To resolve any unmatched names, click the red question mark. This opens the 'Geographical Mapping' dialog box. See Resolving Geographical Data for further instructions.
10. Click the green 'Apply' button.
11. Repeat the previous steps to bind additional 'Geographic' levels. For example, you can bind 'City' and 'State' fields.

12. From the Data panel, drag a measure onto one of the fields in the 'Visual' region of the Binding panel ('Color', 'Shape', 'Size', or 'Text').

This binding will display the measure on the chart using the visual coding you selected, and automatically creates a corresponding legend. See Adding a Sub-Series for more information on using the 'Visual' panel.
13. Click the 'Edit Measure' button, select the desired aggregation method for the measure, and click 'Apply'.

14. (Optional) For any geographical fields that you specified, click the 'Edit Dimension' button, and select the desired ranking for the geographical data. For example, you can display just the top three states according to the measure. Click 'Apply'.

15. (Optional) To create a particular trajectory through the points on the chart, drag a path field to the 'P' region. The values of this field are used to assign the sort order for the plotted data so that connecting lines are drawn between points which are adjacent in the path sort order.
16. Click 'Finish' to close the 'Data Binding' dialog box.
