Working with JavaFX charts

Making charts in JavaFX is easy:

1. Create a list of data in a chart specific format
2. Configure how you want your chart to look

Creating a Pie chart

This chart shows only one dataset as the pie's slices. The bigger a corresponding value, the bigger its slice:

// chapter10/chart/PieChartDemo.java
ObservableList<PieChart.Data> pieChartData =
    FXCollections.observableArrayList(
                new PieChart.Data("Luck", 10),
                new PieChart.Data("Skill", 30),
                new PieChart.Data("Power of Will", 15),
                new PieChart.Data("Pleasure", 5),
                new PieChart.Data("Pain", 40));

The JavaFX PieChart for this looks as follows:

Note

Note that numbers in PieChart.Data are not always percents—the total sum is calculated on each new element and each number represents a share of this total sum.

Additionally, all you need to create PieChart is to choose the title and legend options:

PieChart chart = new PieChart(data);
chart.setTitle...
