Data Visualization CHAPTER 9 177

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 dene 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 shapele. 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.
