Matplotlib - Plot size, how to adjust the size?
提问by Rafael Rodrigues Santos
I'm trying to remove the white space from the plot that I created,please see the photo below:
我正在尝试从我创建的图中删除空白区域，请参见下面的照片：
As it is possible to see, there a big white spot on the right and also on the bottom, how to fix it?, follow down my script:
可以看到，右侧和底部都有一个大白点，如何修复它？，请按照我的脚本进行操作：
fig = plt.figure(figsize=(7,7))
ax1 = plt.subplot2grid((4,3), (0,0),)
ax2 = plt.subplot2grid((4,3), (1,0),)
ax3 = plt.subplot2grid((4,3), (0,1),)
ax4 = plt.subplot2grid((4,3), (1,1),)
data = self.dframe[i]
tes = print_data(data, self.issues, self.color, self.type_user)
tes.print_top(data=data, top=10, ax=ax1, typegraph="hbar", problem=self.issues[i], tone=self.color[i])
tes.print_top(data=data, top=10, ax=ax2, typegraph="prod_bar", problem=self.issues[i], tone=self.color[i])
tes.print_top(data=data, top=10, ax=ax3, typegraph="reg_hbar", problem=self.issues[i], tone=self.color[i])
tes.print_top(data=data, top=10, ax=ax4, typegraph=self.type_user, problem=self.issues[i], tone=self.color[i])
problem = self.issues[i]
plt.tight_layout()
name = problem + str('.PNG')
plt.close(fig)
fig.savefig(name)
Any help will be highly appreciated
任何帮助将不胜感激

You are creating too many subplots!
您正在创建太多子图！
If we look at this line:
如果我们看这一行：
ax1 = plt.subplot2grid((4,3), (0,0),)
We can see the first argument given to subplot2grid are the dimensions of the subplot grid to be made, in this case 4 rows, and 3 columns. You are then plotting in the subplots in the top left of your figure (the second argument given) which leaves a lot of space that's not used.
我们可以看到给 subplot2grid 的第一个参数是要制作的子图网格的尺寸，在本例中为 4 行和 3 列。然后，您将在图形左上角的子图中进行绘图（给出的第二个参数），这留下了很多未使用的空间。
So to solve this, reduce the number of subplots by using:
因此，要解决此问题，请使用以下方法减少子图的数量：
ax1 = plt.subplot2grid((2,2), (0,0),)
Full example:
完整示例：
import numpy as np
import matplotlib.pyplot as plt
data = np.random.randn(25)
fig = plt.figure(figsize=(7,7))
ax1 = plt.subplot2grid((2,2), (0,0),)
ax2 = plt.subplot2grid((2,2), (1,0),)
ax3 = plt.subplot2grid((2,2), (0,1),)
ax4 = plt.subplot2grid((2,2), (1,1),)
ax1.plot(data)
ax2.plot(data)
ax3.plot(data)
ax4.plot(data)
plt.show()

you can use
plt.subplots_adjust(left=0.09, bottom=0.07, right=0.98, top=0.97, wspace=0.2 , hspace=0.17 )to adjust the window.
But the issue is that a lot of the space in your plot is empty
maybe you should change
plt.subplot2grid((4,3)... to plt.subplot2grid((2,2)
可以
plt.subplots_adjust(left=0.09, bottom=0.07, right=0.98, top=0.97, wspace=0.2 , hspace=0.17 )用来调整窗口。但问题是你的情节中的很多空间都是空的，也许你应该改变
plt.subplot2grid((4,3)......plt.subplot2grid((2,2)
