我可以创建此图:
import matplotlib.pyplot as plt
x = range(1, 16)
zero = [0] * 15
pointfive = [0.5] * 15
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(x, days, 'moccasin')
ax1.set_ylabel('days', color='moccasin')
ax2 = ax1.twinx()
ax2.plot(x, probs, "turquoise")
ax2.set_ylabel('probabilities', color="turquoise")
ax3 = fig.add_subplot(111)
ax3.plot(x, zero , "--", color="moccasin")
ax4 = fig.add_subplot(111)
ax4.plot(x, pointfive , "--", color="turquoise")
fig.text(0.5, 0.04, 'days to lat, ha='center')
这些让我想改变的事情:
弯曲的虚线应根据右侧的y轴比例绘制
应当添加通用的x标签和标题
这说明了我想要的更改:
我怎么做?谢谢!
最佳答案
您已经定义了轴ax1(左)和ax2(右)。只需使用这些来选择要绘制的轴:
x = range(1, 16)
y1 = 10*np.random.random(size=len(x))
y2 = np.random.random(size=len(x))
zero = [0] * 15
pointfive = [0.5] * 15
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(x, y1, 'moccasin')
ax1.set_ylabel('days', color='moccasin')
ax2 = ax1.twinx()
ax2.plot(x, y2, "turquoise")
ax2.set_ylabel('probabilities', color="turquoise")
ax1.plot(x, zero , "--", color="moccasin")
ax2.plot(x, pointfive , "--", color="turquoise")
ax1.set_xlabel('days to lat')
ax1.set_title('TITLE')
