# 折线图
x = np.array([1, 2, 3, 4, 5, 6, 7, 8])
y = np.array([2, 4, 6, 8, 10, 12, 14, 16])
plt.plot(x, y, 'b', lw=5)  # x代表的是x轴，y代表的是Y轴，b代表的是颜色 lw是线宽 plot是折线图  (x,y)构成坐标，x与y一一对应


# 柱状图
x = np.array([1,2,3,4,5,6,7,8])
y = np.array([13,25,17,36,21,16,10,15])
plt.bar(x, y)  # x与y一一对应
plt.show()  # 将图片进行显示
