Question

我正在尝试用Java制作3D图。对此我使用jmathplot。我有搜索找到一种方法来为我的污点添加标题，并且发现使用如下BaseLabel应该有效。但是，当我尝试运行我的程序时，我得到java.lang.ArrayIndexOutOfBoundsException: 2 out of bound exception。我无法弄清楚为什么会这样。看起来好像它是摆动面板而不是图形。当删除将BaseLabel添加到我的绘图的行时，代码工作正常。希望你们中的一些人能够提供帮助。

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;

import javax.swing.*; //JFrame;

import org.math.plot.Plot3DPanel;
import org.math.plot.plotObjects.BaseLabel;

public class plotFrame1
{

    private JFrame frame = new JFrame("tester plot");
    private JPanel panel = new JPanel();

    public plotFrame1()
    {
        double[][] xyz = new double[4][3];
        double[][] widths = new double[4][3];
        int ds = 0;
        for(int i = 0; i < xyz.length; i++)
        {
            xyz[i][0] = ds;
            xyz[i][1] = ds;
            xyz[i][2] = ds;
            ds += 1;
            widths[i][0] = 1;
            widths[i][1] = 1;
            widths[i][2] = 1;
        }

        Plot3DPanelPackage plot = new Plot3DPanelPackage();
        BaseLabel title = new BaseLabel("...My nice plot...", Color.BLACK, 0.5, 1.1);
        plot.addPlotable(title);
        String n = "test";
        Color c = Color.black;
        plot.addPackagePlot(xyz,widths,c,n);

        panel.setLayout(new BorderLayout());
        panel.add(plot);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(panel);
        frame.pack();
        frame.setVisible(true);
    }

    class Plot3DPanelPackage extends Plot3DPanel
    {
        public int addPackagePlot(double[][] _xyz, double[][] _measures, Color c, String n)
        {
            return addPlot(new PackagePlot3D(_xyz,_measures,c,n));
        }
    }

    public static void main(String args[]) {
        plotFrame1 ny = new plotFrame1();
    }

}

整个错误如下：
