This class is a JPanel which can be added to any JPanel or JFrame. The viewer implements the following features: - It displays the chart you set with the setChart() method. - It implements scroll bars and zoom in/out buttons. - It can automatically change the cursor when the pointer moves over a value in the chart. Example of use: public class SimpleJExample extends JFrame { JChartViewer chartViewer= new JChartViewer(); public SimpleJExample() { this.setTitle("RChart for Swing example"); this.setResizable(false); this.getContentPane().setLayout(new java.awt.BorderLayout()); this.setSize(new Dimension(500,500)); this.getContentPane().add("Center", chartViewer); this.doLayout(); // create default chart ChartLoader loader=new ChartLoader(); loader.loadFromFile("examples/lineChart.txt",true); chartViewer.setChart(loader.build(false,false)); this.show(); } }
