从Qt生成的代码在pyqt5中集成matplotlib图

如何将matplot lib与pyqt5集成?我已经尝试了很多集成,但是无法做到。基本上,我想在相同的主窗口中单击一个按钮时显示我的图。

self.pushButton_2.clicked.connect(self.plot)

下面是整个代码,是QT设计器生成的部分代码。

使用此代码,我应该能够跳到绘图功能

 def plot(self):
        plt.magnitude_spectrum(self.y_time, self.sr)
        plt.show()

得到频谱图。

使用pyqt5从Qt设计器生成的示例代码:

from PyQt5 import QtCore, QtGui, QtWidgets
import matplotlib.pyplot as plt

class Ui_MainWindow(object):

    def plot():
        plt.magnitude_spectrum(rate and data)
        plt.show()


    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(800, 600)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(160, 190, 85, 27))
        self.pushButton.setObjectName("pushButton")
        self.pushButton_2 = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton_2.setGeometry(QtCore.QRect(40, 110, 85, 27))
        self.pushButton_2.clicked.connect(self.plot)
        self.pushButton_2.setObjectName("pushButton_2")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 27))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)
        self.statusbar = QtWidgets.QStatusBar(MainWindow)
        self.statusbar.setObjectName("statusbar")
        MainWindow.setStatusBar(self.statusbar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.pushButton.setText(_translate("MainWindow", "display plot "))
        self.pushButton_2.setText(_translate("MainWindow", "load audio "))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())
