具有不同 styles 的同一圖上的多個視圖

Question

我正在嘗試比較社區檢測算法的輸出，並且我想進行並排比較。 這個想法是，我將有兩個 windows 顯示相同的圖形布局，並且我根據所選的 output 為節點和邊緣着色。 一個簡單的例子是這樣的：

我能夠生成圖形並創建視圖，但我沒有發現如何在 Graphstream 中為兩個圖形強制使用相同的圖形布局或基於 Graphstream 視圖分配不同的 UI 屬性。

這個事情誰有經驗？

在一個玩具示例中，我似乎得到了類似的結果，盡管不一樣。 問題開始了，一旦我使用了數千個節點，似乎布局就完全不同了。 不幸的是，我無法為這種情況提供數據集。 這是一個更大數據的示例：

兩個圖都有相同的布局管理器（SpringBox）並使用相同的數據。

我正在使用 Java 8、Graphstream 2.0 和 Swing

編輯：我發現，可以將Random作為種子傳遞給Layout ，但不幸的是它不會產生相同的圖表。

Answer 1

您必須添加圖表，但這是我想出的 GUI。

我創建了一個JFrame和兩個主要的JPanels 。 每個主JPanel內部都有一個視圖JPanel和一個JComboBox 。 我為兩個視圖JPanels提供了首選大小，因為它們沒有任何 Swing 組件來調整它們的大小。 我希望您創建的圖表將調整視圖JPanels的大小。

我在整個 GUI 中使用了BorderLayouts 。 我以自己的方法創建了每個JPanel ，因此我可以測試不同的 Swing 布局管理器。 如果您想要更多空白，您可以調整兩個主要JPanel方法中的空白邊框。

這是完整的可運行代碼。

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;

    }
