matplotlib绑定到PyQt5（无菜单）

很简单的实现matplotlib绑定到PyQt5

【知识点】

1 import matplotlib
2 matplotlib.use("Qt5Agg")
3
4 from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
5 from matplotlib.figure import Figure

【效果图】

13         fig = Figure(figsize=(width, height), dpi=100)
14         FigureCanvas.__init__(self, fig)
15         self.setParent(parent)

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

22         self.axes2 = fig.add_subplot(212)
23         x = np.arange(0, 5, 0.1)
24         self.axes2.plot(x, np.sin(x), x, np.cos(x))

31     w = Widget()
32     w.show()
