我正在尝试比较社区检测算法的输出，并且我想进行并排比较。这个想法是，我将有两个窗口显示相同的图形布局，并根据所选输出为节点和边缘着色。一个简单的例子是这样的：GUI 示例视图

我能够生成图形并创建视图，但我没有发现如何在 Graphstream 中为两个图形强制使用相同的图形布局或基于 Graphstream 视图分配不同的 UI 属性。

这个事情谁有经验？

在一个玩具示例中，我似乎得到了类似的结果，尽管不一样。问题开始了，一旦我使用了数千个节点，似乎布局就完全不同了。不幸的是，我无法为这种情况提供数据集。这是一个更大数据的示例：

在此处输入图像描述 两个图都有相同的布局管理器（SpringBox）并使用相同的数据。

我正在使用 Java 8、Graphstream 2.0 和 Swing

编辑：我发现，可以Random作为种子传递给Layout，但不幸的是它不会产生相同的图表。

您必须添加图表，但这是我想出的 GUI。

多个视图

我创建了一个JFrame和两个主要的JPanels. 每个 main 里面都有JPanel一个视图JPanel和一个JComboBox. 我为这两个视图提供了首选大小，JPanels因为它们没有任何 Swing 组件来调整它们的大小。我希望您创建的图表将调整视图的大小JPanels。

我BorderLayouts在整个 GUI 中都使用过。JPanel我用自己的方法创建了每一个，所以我可以测试不同的 Swing 布局管理器。JPanel如果您想要更多空白，您可以在两种主要方法中调整空白边框。

这是完整的可运行代码。

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

import javax.swing.BorderFactory;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class MultipleViews implements Runnable {

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new MultipleViews());
    }

    @Override
    public void run() {
        JFrame frame = new JFrame("Multiple Views");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        frame.add(createPanel1(), BorderLayout.BEFORE_LINE_BEGINS);
        frame.add(createPanel2(), BorderLayout.AFTER_LINE_ENDS);
        
        frame.pack();
        frame.setLocationByPlatform(true);
        frame.setVisible(true);
    }
    
    private JPanel createPanel1() {
        JPanel panel = new JPanel(new BorderLayout(5, 5));
        panel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
        panel.add(createView1(), BorderLayout.CENTER);
        
        JComboBox<Transaction> lCCommunitiesNames = new JComboBox<>();
        panel.add(lCCommunitiesNames, BorderLayout.AFTER_LAST_LINE);
        
        return panel;
    }
    
    private JPanel createView1() {
        JPanel panel = new JPanel(new BorderLayout());
        panel.setBackground(Color.gray);
        panel.setPreferredSize(new Dimension(750, 350));
        return panel;
    }
    
    private JPanel createPanel2() {
        JPanel panel = new JPanel(new BorderLayout(5, 5));
        panel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
        panel.add(createView2(), BorderLayout.CENTER);
        
        JComboBox<Transaction> minoltaCommunitiesNames = new JComboBox<>();
        panel.add(minoltaCommunitiesNames, BorderLayout.AFTER_LAST_LINE);
        
        return panel;
    }

    private JPanel createView2() {
        JPanel panel = new JPanel(new BorderLayout());
        panel.setBackground(Color.blue);
        panel.setPreferredSize(new Dimension(750, 350));
        return panel;
    }
    
    public class Transaction {
        
    }

}
