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_())
