具体用到了matplotlib.backends.backend_qt5agg.FigureCanvasQTAgg

直接上代码(这里给出的只是一个简单的框架，告诉你怎么去写)：

# -*- coding: utf-8 -*-'''TODO:LQD'''import sysimport numpy as npimport matplotlib.pyplot as pltfrom matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FCfrom PyQt5.QtWidgets import QApplication, QPushButton, QMainWindow, QVBoxLayout, QWidget class QtDraw(QMainWindow): flag_btn_start = True def __init__(self): super(QtDraw, self).__init__() self.init_ui() def init_ui(self): self.resize(800, 600) self.setWindowTitle('PyQt5 Draw') # TODO:这里是结合的关键 self.fig = plt.Figure() self.canvas = FC(self.fig) self.btn_start = QPushButton(self) self.btn_start.setText('draw') self.btn_start.clicked.connect(self.slot_btn_start) widget = QWidget() layout = QVBoxLayout() layout.addWidget(self.canvas) layout.addWidget(self.btn_start) widget.setLayout(layout) self.setCentralWidget(widget) def slot_btn_start(self): try: ax = self.fig.add_subplot(111) x = np.linspace(0, 100, 100) y = np.random.random(100) ax.cla() # TODO:删除原图，让画布上只有新的一次的图 ax.plot(x, y) self.canvas.draw() # TODO:这里开始绘制 except Exception as e: print(e) def ui_main(): app = QApplication(sys.argv) w = QtDraw() w.show() sys.exit(app.exec_()) if __name__ == '__main__': ui_main()

以上这篇pyqt5与matplotlib的完美结合实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
