FIGURE 9-13 Indicator types
After selecting a set of indicators, you associate the set with a value in your dataset or with
an expression, such as a comparison of a dataset value to a goal. You then dene the rules
that determine which indicator properly represents the status. For example, you might create
an expression that compares SalesAmount to a goal. You could then assign a green check
mark if SalesAmount is within 90 percent of the goal, a yellow exclamation point if it is within
50 percent of the goal, and a red X for everything else.
Maps
A map element is a special type of data visualization that combines geospatial data with other
types of data to be analyzed. You can use the built-in Map Gallery as a background for your
data, or you can use an ESRI shapele. For more advanced customization, you can use SQL
Server spatial data types and functions to create your own polygons to represent geographi-
cal areas, points on a map, or a connected set of points representing a route. Each map can
have one or more map layers, each of which contains spatial data for drawing the map, ana-
lytical data that will be projected onto the map as color-coded regions or markers, and rules
for assigning colors, marker size, and other visualization properties to the analytical data. In
addition, you can add Bing Maps tile layers as a background for other layers in your map.
