matplotlib绑定到PyQt5（无菜单）

很简单的实现matplotlib绑定到PyQt5

【知识点】

 import matplotlib
 matplotlib.use("Qt5Agg")

 from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
 from matplotlib.figure import Figure

【效果图】

【源代码】

 import numpy as np
 import matplotlib
 matplotlib.use("Qt5Agg")

 from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
 from matplotlib.figure import Figure

 from PyQt5 import QtWidgets

 class Widget(FigureCanvas):
     def __init__(self, parent=None, width=5, height=4, dpi=100):
         fig = Figure(figsize=(width, height), dpi=100)
         FigureCanvas.__init__(self, fig)
         self.setParent(parent)

         # 散点图
         self.axes = fig.add_subplot(211)
         self.axes.scatter(np.random.rand(20), np.random.rand(20))

         # 折线图
         self.axes2 = fig.add_subplot(212)
         x = np.arange(0, 5, 0.1)
         self.axes2.plot(x, np.sin(x), x, np.cos(x))

         self.setWindowTitle("示例：matplotlib 绑定到 PyQt5")

 if __name__ == "__main__":
     import sys
     app = QtWidgets.QApplication(sys.argv)
     w = Widget()
     w.show()
     sys.exit(app.exec_())
