PyQt4에 Matplotlib 그래프를 포함하는 방법: 대화형 시각화를 위한 단계별 가이드?

import sys
from PyQt4 import QtGui

from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt4agg import NavigationToolbar2QT as NavigationToolbar
from matplotlib.figure import Figure

<code class="python">class Window(QtGui.QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # ...
        # The rest of the Window initialization, including figure, canvas, toolbar, and button creation goes here.</code>

<code class="python">self.figure = Figure()
self.canvas = FigureCanvas(self.figure)</code>

<code class="python">self.toolbar = NavigationToolbar(self.canvas, self)</code>

<code class="python">self.button = QtGui.QPushButton('Plot')
self.button.clicked.connect(self.plot)</code>

<code class="python">def plot(self):
    # Generate random data
    data = [random.random() for i in range(10)]

    # Create an axis
    ax = self.figure.add_subplot(111)

    # Clear the existing graph
    ax.clear()

    # Plot the data
    ax.plot(data, '*-')

    # Refresh the canvas
    self.canvas.draw()</code>

<code class="python">layout = QtGui.QVBoxLayout()
layout.addWidget(self.toolbar)
layout.addWidget(self.canvas)
layout.addWidget(self.button)
self.setLayout(layout)

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    main = Window()
    main.show()

    sys.exit(app.exec_())</code>
