简单图例
创建一个简单的图。
import matplotlibimport matplotlib.pyplot as pltimport numpy as np# Data for plottingt = np.arange(0.0, 2.0, 0.01)s = 1 + np.sin(2 * np.pi * t)fig, ax = plt.subplots()ax.plot(t, s)ax.set(xlabel='time (s)', ylabel='voltage (mV)',title='About as simple as it gets, folks')ax.grid()fig.savefig("test.png")plt.show()
