如何使我的 DataFrame.plot 子图在线发布？

Question

我试图了解 pandas.DataFrame.plot 的工作原理，但坚持将多个子图排成一行。我感到很困惑，所以我的问题可能听起来很奇怪。但如果能提供任何帮助，我将不胜感激。

recent_grads.plot(x = "Women", y = "Median", kind = "scatter", subplots = True, figsize=(6, 6), layout = (2,2), sharex = False)
recent_grads.plot(x = "Men", y = "Median", kind = "scatter", subplots = True, figsize=(6, 6), layout = (2,2), sharex = False)

我正在将我的子图放在另一个子图上，但我希望它们排成一行。

Answer 1

你可以从matplotlib.pyplot使用plt.subplots

import matplotlib.pyplot as plt
fig, ax = plt.subplots(nrows=1, ncols=2)
fig.set_size_inches(6, 6)
plt.subplots_adjust(wspace=0.2)
recent_grads.plot(x = "Women", y = "Median", kind = "scatter", ax=ax[0], sharex = False)
recent_grads.plot(x = "Men", y = "Median", kind = "scatter", ax=ax[1], sharex = False)

Answer 2

你只需要修改layout:

recent_grads.plot(x = "Women", y = "Median", kind = "scatter", subplots = True, figsize=(6, 6), layout = (1, 1), sharex = False)
recent_grads.plot(x = "Men", y = "Median", kind = "scatter", subplots = True, figsize=(6, 6), layout = (1, 2), sharex = False)

另一种方法是创建Axes 对象并明确指定它们：

from matplotlib import pyplot as plt

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(6, 6))

ax1, ax2 = axes

recent_grads.plot(x = "Women", y = "Median", kind = "scatter", ax=ax1)
recent_grads.plot(x = "Men", y = "Median", kind = "scatter", ax=ax2)
