Cross-Tab
Use the Cross-Tab layout when mapping on a Cross-Tab object. A Cross-Tab
map does not require groups or summary fields.
OLAP
Use the OLAP layout when mapping on an OLAP grid. An OLAP map does
not require groups or summary fields.
Note:
If there is no map associated with the data you specify, then an empty block
will appear unless the section that the map is placed in has been formatted
to suppress if blank.
Map types
The Map Expert also provides five basic map types, each suitable for a
different strategy of data analysis. When deciding which map type best fits
your report, you should consider the type of data you want to analyze. For
example, if you want the map to display one data item for each geographic
division (city, state, country, and so on), then you might use a Ranged, Dot
Density, or Graduated map. On the other hand, if you want the map to display
more than one value for each new geographic division, then you could use
a Pie Chart map or a Bar Chart map. The following is an overview of the
main map types and their most common uses.
Ranged
A Ranged map breaks the data into ranges, assigns a specific color to each
range, then color codes each geographic area on the map to display the
range. For example, you could create a map that displays Last Year's Sales
by Region. If you have sales ranging from zero to 100,000, you might give
the map five ranges, with equal intervals of 20,000 each. You could use
shades of red (going from dark to light red) to color code each region
according to those sales figures. Then you could use this map to see where
sales are the highest.
With equal intervals, you might end up with all your regions ranging between
zero and 20,000, except perhaps one region (for example, California) that
might have exceptionally high sales (such as 98,000). This map would be a
