Creating maps

304 Crystal Reports User’s Guide

Where to place a map

When you choose where to place the map, you determine the amount of data

that will be included in the map. For example, if you place the map in the

Report Header section, the map includes data for the entire report. If you

place it in a Group Header or Group Footer section, it displays group-specific

data. This choice will also determine whether the map prints once for the

entire report, or many times (once for each instance of a given group).

Note: If your report contains subreports, you can place maps in those

subreports as well.

Drill-down with maps

Not only is mapping a means of presenting data—it is also an analysis tool.

Move your cursor over a section of the map on the Preview tab, so that the

pointer becomes a Drill-down cursor, then double-click to view the underlying

details for that section of the map.

Note: If you drill down on a region that has no data associated with it, you will

get a message saying, “There are no detail records for that {Region Name}.”

Creating maps

The process for creating a map varies depending on the data you are mapping

on. The following sections detail the mapping process for each map layout.

Mapping on details fields (Advanced layout)

The Advanced layout allows you to create a map based on specific values.

With an Advanced layout, you can create a map without the need for a

summary field by using values that appear in the Details section of your report.

To create a map based on the Advanced layout, you must specify two things:

• Conditions (there can be two).

• Value (there must be only one value).

Condition

The condition is used to indicate where to plot the data on a map. This condition

must be a string field. In order for a map to be generated, the field should

contain geographic information. For example, a map showing last year’s sales

for each country uses the Country field as the condition. Each time the

condition changes (the country changes), that area on the map is highlighted.
