Creating Charts in JavaFX - JavaFX 8: A Definitive Guide to Building Desktop, Mobile, and Embedded Java Clients - page 352

Some Modifications
Although the result of the simple example already looks good, we can tweak both the code and the rendering. First of
all, the example uses two lines of code for creating the PieChart and populating it with data:
PieChart pieChart = new PieChart();
pieChart.setData(getChartData());
Because PieChart has a single argument constructor as well, the preceding code snippets can be replaced
as follows.
PieChart pieChart = new PieChart(getChartData());
Apart from the properties defined on the abstract Chart class, a PieChart has the following properties.
BooleanProperty clockwise
ObjectProperty<ObservableList<PieChart.Data>>data
DoubleProperty labelLineLength
BooleanProperty labelsVisible
DoubleProperty startAngle
We covered the data property in the previous section. Some of the other properties are demonstrated in the next
code snippet. Listing 8-2 contains a modified version of the start() method.
Listing 8-2. Modified Version of the PieChart Example
public void start(Stage primaryStage) {
PieChart pieChart = new PieChart();
pieChart.setData(getChartData());
pieChart.setTitle("Tiobe index");
pieChart.setLegendSide(Side.LEFT);
pieChart.setClockwise(false);
pieChart.setLabelsVisible(false);
primaryStage.setTitle("PieChart");
StackPane root = new StackPane();
root.getChildren().add(pieChart);
primaryStage.setScene(new Scene(root, 400, 250));
primaryStage.show();
}
Because we used the Side.LEFT field in the new code, we have to import the Side class in our application as well.
This is done by adding the line
import javafx.geometry.Side
in the import block of the code.
Running this modified version results in the modified output shown in Figure 8-4 .
