pyqt5 QWidget 嵌入 pyqtgraph 举例

当然可以嵌入，以下是一个简单的代码示例：

import sys
import pyqtgraph as pg
from PyQt5.QtWidgets import QApplication, QWidget, QVBoxLayout
from PyQt5.QtCore import Qt


class GraphWindow(QWidget):
    def __init__(self):
        super(GraphWindow, self).__init__()

        # Set main window properties
        self.setWindowTitle('PyQtGraph Example')
        self.setGeometry(100, 100, 640, 480)
        self.setWindowFlags(Qt.WindowCloseButtonHint)

        # Create a widget for the graph
        self.graph_widget = pg.PlotWidget()

        # Create some data to plot
        x = [1, 2, 3, 4, 5]
        y = [1, 0, 3, 2, 4]

        # Plot the data
        self.plot = self.graph_widget.plot(x, y)

        # Add the graph widget to the main window
        layout = QVBoxLayout()
        layout.addWidget(self.graph_widget)
        self.setLayout(layout)


# Create the application and window
app = QApplication(sys.argv)
window = GraphWindow()
window.show()

# Run the application
sys.exit(app.exec_())

这是一个简单的 Pyqt5 QWidget 嵌入 pyqtgraph 的示例代码。可以根据需要修改和扩展。
