多个Y轴的水平缩放的堆叠水平图

问题描述 投票:2回答:1

嗨,我正在尝试创建:

  1. 水平堆积图
  2. 在两个图上都具有辅助轴
  3. [在轴上具有不同的比例尺-不幸的是,我的两个Y轴当前每个子图具有相同的比例尺...:(

当前代码:

#  Create axes
fig, (ax1, ax2) = plt.subplots(1, 2)
fig.suptitle("XYZ")
fig.set_figheight(5)
fig.set_figwidth(15)
# First graph
ax1.scatter(
    df_PTA_clip_pstar["start_time"],
    df_PTA_clip_pstar["pstar"],
    s=5,
    c="black",
    label="P*",
)
plt.ylabel("P*")
ax1.scatter(df_PTA_clipkh["start_time"], df_PTA_clipkh["kh"], s=2, c="cyan", label="Kh")
ax1.secondary_yaxis("right")
plt.ylabel("Kh")

# Second graph - will add the correct data to this once first graph fixed
ax2.scatter(x, y, s=5, c="Red", label="P*")
ax2.scatter(x, z, s=5, c="Green", label="Kh")

ax2.secondary_yaxis("right")
plt.tight_layout()
plt.legend()
plt.show()

您可以在每个轴对象上使用.twinx()方法,因此您可以在共享x轴的同一个轴对象上具有两个图:

import matplotlib.pyplot as plt import numpy as np # Create axes fig, (ax1, ax2) = plt.subplots(1, 2) ## First subplot x = np.random.random_sample(100) y = np.random.random_sample(100) ax1.set_xlim(0, 2) ax1.scatter(x, y, s=5, c="black") ax11 = ax1.twinx() x = 1 + x y = 1 + np.random.random_sample(100) ax11.scatter(x, y, s=5, c="red") ## Second subplot x = 2 * np.random.random_sample(100) - 1 y = np.random.random_sample(100) ax2.set_xlim(-1, 2) ax2.scatter(x, y, s=5, c="blue") ax21 = ax2.twinx() x = 1 + x y = 10 + np.random.random_sample(100) ax21.scatter(x, y, s=5, c="orange") plt.show()
