Jupyter 使 3D matplotlib 图变得非常小

Question

阅读了该网站上有关在 Jupyter 中调整图形大小和设置图形大小限制的许多帖子后，我几乎确信在 3D 绘图方面存在一些不同。

这是 Jupyter 不断回馈给我的 3D 散点图，尽管尝试了许多 figsize 和 dpi= 设置（在 plt.figure() 或 plt.rcParams() 中），

这是我的数据和我当前的代码，

%pylab inline
pylab.rcParams['figure.figsize'] = (20, 16)
pylab.rcParams['figure.dpi'] = 200

import matplotlib.pyplot as plt
import matplotlib

from mpl_toolkits.mplot3d import Axes3D

# data1

fig = plt.figure()

ax = fig.add_subplot(111, projection='3d')

ax.scatter(data1.a_close, data1.g_close, data1.m_close)

我做错了什么？

编辑：我使用的是 Mac (10.11)，如果这提供了一些详细信息，这些都是我的 pip 安装包。我也尝试卸载并重新安装jupyter，但这并没有帮助

Answer 1

这是由于 matplotlib 3.0.0 中的一个错误。它不应该出现在 matplotlib 3.0.1 中。

您的选择：

• 更新到 matplotlib 3.0.1

• 在绘图之前在你的 jupyter notebook 中设置以下选项

  %config InlineBackend.print_figure_kwargs = {'bbox_inches':None}
  

• 使用%matplotlib notebook 后端而不是%matplotlib inline。

Answer 2

尝试替换

%pylab inline
pylab.rcParams['figure.figsize'] = (20, 16)
pylab.rcParams['figure.dpi'] = 200

import matplotlib.pyplot as plt
import matplotlib

与

%matplotlib inline

import matplotlib.pyplot as plt
import matplotlib

matplotlib.rcParams['figure.figsize'] = (20, 16)
matplotlib.rcParams['figure.dpi'] = 200

Answer 3

在我的 Mac 上有时也会发生这种情况。

先用这个：

import matplotlib.pyplot as plt
import matplotlib
%matplotlib inline

matplotlib.rcParams['figure.figsize'] = (20, 16)
matplotlib.rcParams['figure.dpi'] = 200

我的情况的诀窍：首先导入，然后使用%matplotlib inline 命令。但是，似乎是一个错误。
