将jzy3d.canvas投射到awt.component

Question

我需要将jzy3d
canvas强制转换为java.awt.component，我想使用JCombobox和按钮在框架中显示图表，但是当我要将画布强制转换为component时，程序被删除。谢谢您的回答。我已经尝试过了，对我没有帮助。

Answer 1

这为我工作。简单的解决方案，当我将jzy3d画布放到画布上并放入面板中时。

Chart chart = AWTChartComponentFactory.chart(Quality.Advanced, IChartComponentFactory.Toolkit.swing);   
ChartScene scene = chart.getScene();
AWTCameraMouseController controller = new AWTCameraMouseController(chart);
Component canvas = (Component) chart.getCanvas();
canvas.addMouseListener(controller);
canvas.addMouseMotionListener(controller);
canvas.addMouseWheelListener(controller);
centerPanel.add(canvas, BorderLayout.CENTER);
