How to increase image size in matplotlib and pandas?
提问by Blue Moon
I am trying to increase the size of the image resulting from this function:
我正在尝试增加此功能产生的图像的大小：
plt.figure()); data_ordertotal.plot(); plt.legend(loc='best')
I tried this but the size remains the same
我试过了，但大小保持不变
plt.figure(figsize=(40,40)); data_ordertotal.plot(); plt.legend(loc='best')
I am coding using spyder and the output in the console remains always the same size. Any solution? Thanks
我正在使用 spyder 进行编码，并且控制台中的输出始终保持相同的大小。有什么解决办法吗？谢谢

I guess you're using pandas, and you should use:
我猜你正在使用Pandas，你应该使用：
data_ordertotal.plot(figsize=(40,40))
It doesn't work with plt.figure(figsize=(40,40))because pandas will create a new figure if you don't pass it an axeobject.
它不起作用，plt.figure(figsize=(40,40))因为如果您不将axe对象传递给Pandas，它会创建一个新图形。
It would work with:
它将与：
fig, ax = plt.subplots(1, 1, figsize=(40,40))
data_ordertotal.plot(ax=ax)
...Assuming you're using pandas, if not you should detail a bit more what is data_ordertotal
...假设您使用的是Pandas，如果不是，您应该详细说明一下是什么 data_ordertotal

when you create a figure change the figsize. The dimension are in inches
创建图形时，请更改图形大小。尺寸单位为英寸
import matplotlib.pyplot as plt
plt.figure(num=1, figsize=(40, 40), dpi=80, facecolor='w', edgecolor='k')
That works for me in spyder.
这在 spyder 中对我有用。
fig = plt.gcf()
fig.set_size_inches(18.5, 10.5)
should also work
也应该工作
