pyqt5与matplotlib的完美结合实例
具体⽤到了matplotlib.backends.backend_qt5agg.FigureCanvasQTAgg
直接上代码(这⾥给出的只是⼀个简单的框架，告诉你怎么去写)：

x = np.linspace(0, 100, 100)
y = np.random.random(100)
ax.cla() # TODO：删除原图，让画布上只有新的⼀次的图
ax.plot(x, y)
self.canvas.draw() # TODO：这⾥开始绘制
except Exception as e:
print(e)
def ui_main():
app = QApplication(sys.argv)
w = QtDraw()
w.show()
<_())
if __name__ == '__main__':
ui_main()
以上这篇pyqt5与matplotlib的完美结合实例就是⼩编分享给⼤家的全部内容了，希望能给⼤家⼀个参考，也希望⼤家多多⽀持。
