使用 seaborn 将次要网格线添加到 matplotlib 图 [英] Add minor gridlines to matplotlib plot using seaborn

问题描述

我是Seaborn软件包的粉丝，因为他使用Matplotlib制作漂亮的图.但是我似乎无法弄清楚如何在绘图中显示次要网格线.

I'm a fan of the Seaborn package for making nice-looking plots using Matplotlib. But I can't seem to figure out how to show minor gridlines in my plots.

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sbn

x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)

fig, ax = plt.subplots(1, 1)
ax.scatter(x, y)

ax.grid(b=True, which='major')
ax.grid(b=True, which='minor')

给予:

这里有什么想法吗?还有关于如何调整出现的 Seaborn 网格线样式的任何想法......特别是，我很想使它们更窄.

Any thoughts here? Also any thoughts on how to adjust the style of the Seaborn gridlines that do show up...in particular, I'd love to make them narrower.

推荐答案

结合朱卓恩的答案和tcaswell的提示:

Wound up combining CT Zhu's answer with tcaswell's hint:

import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
import seaborn as sbn

x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)

fig, ax = plt.subplots(1, 1)

ax.scatter(x, y)
ax.get_xaxis().set_minor_locator(mpl.ticker.AutoMinorLocator())
ax.get_yaxis().set_minor_locator(mpl.ticker.AutoMinorLocator())
ax.grid(b=True, which='major', color='w', linewidth=1.0)
ax.grid(b=True, which='minor', color='w', linewidth=0.5)
