canvas - 如何将风玫瑰图嵌入 GUI

Question

以下代码准备风玫瑰图并将其作为图像添加到 GUI 中（请参见附图风玫瑰图）。有什么办法可以在 GUI 上显示原始图形？提前致谢！

import io
import sys
from PyQt5 import QtWidgets, QtGui
import matplotlib.pyplot as plt
import numpy as np
from windrose import WindroseAxes


class MainWindow(QtWidgets.QMainWindow):

    def __init__(self, *args, **kwargs):
        super(MainWindow, self).__init__(*args, **kwargs)

        ax =self.windrose_fun()
        buff = io.BytesIO()
        plt.savefig(buff, format="jpeg")
        label = QtWidgets.QLabel()
        pixmap =QtGui.QPixmap()
        pixmap.loadFromData(buff.getvalue())
        label.setPixmap(pixmap)
        label.show()

    def windrose_fun(self):
        ws = np.random.random(500) * 6
        wd = np.random.random(500) * 360
        ax = WindroseAxes.from_ax()
        ax.bar(wd, ws, normed=True, opening=0.8, edgecolor='white')
        ax.set_legend(bbox_to_anchor=(0.94, 0.84))
        return(ax)

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    w = MainWindow()
    app.exec_()
