如何修改函数输出图像的大小pandas.DataFrame.plot？

I tried:

我试过：

plt.figure (figsize=(10,5))

and

和

%matplotlib notebook

but none of them work.

但它们都不起作用。

Answer 1

Try this:

尝试这个：

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,5));

df.plot(figsize=(10,5));

EDIT

编辑

The size in figsize=(10,5)is given in inches, unless dpiparam is specified, when it would be in pixels.

in 的大小在figsize=(10,5)中给出inches，除非dpi指定了 param ，否则它将以像素为单位。

Answer 2

If you want to make a change global to the whole notebook:

如果要对整个笔记本进行全局更改：

import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams["figure.figsize"] = [10, 5]
