144 ChArting And MultiMediA Figure 3.9 Plot chart. Plot Charts Also referred to as scattered plots, plot charts show the distribution of data points along one or two dimensions (Figure 3.9). Unlike bubble charts, points have no dimension, although they can have different shape and color. Flex Built-in chart components The Flex framework comes with a set of built-in components to manipulate and render charts. If you are using the designer, charts are grouped into a specific folder, as in Figure 3.10. My First chart in Flex In this section we will build our first chart-based Flex application. We will try to exploit as much as possible the facilities provided by the design view. As we will see, the procedure is pretty similar to the one illustrated in Section 1, when we built a list-based application. The steps are the same: · Defineadataservice/source. · Createaninstanceofachart. · Definethemappingbetweenthedataandthechart. Figure 3.10 Charts in the design view.
