圖和子圖刻度標簽重疊

Question

我想把四個子圖放在一個圖上。 我想要的東西是：

1- 該圖引入了自己的 x 和 y 標簽，我不希望那樣。

2-我想知道是否可以在所有子圖的標簽中為 y 軸標簽使用相似的值

3-我想要的實際圖可以包含大到 3x3（最多 9 個子圖）的子圖。 有沒有辦法制作某種可以從每個子圖的數據框中提取數據並繪制圖形的函數？

這是我使用的代碼和輸出圖。

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
  
fig, (df_256,df_128,df_64,df_32) = plt.subplots(4, 2, sharex='col', sharey='row')
file_locn = ''r'C:\Users\me\Desktop\output.xlsx'''
df = pd.read_excel(file_locn, sheet_name='1', header=[0,1])
   
#print(df)

df_256 = df.xs(256, axis=1, level=0)
df_128 = df.xs(128, axis=1, level=0)
df_64 = df.xs(64, axis=1, level=0)
df_32 = df.xs(32, axis=1, level=0)

ax1 = fig.add_subplot(221)
ax2 = fig.add_subplot(222)
ax3 = fig.add_subplot(223)
ax4 = fig.add_subplot(224)

ax1.set_xscale('symlog', base=2)
ax2.set_xscale('symlog', base=2)
ax3.set_xscale('symlog', base=2)
ax4.set_xscale('symlog', base=2)

ax1.set_yscale('log')
ax2.set_yscale('log')
ax3.set_yscale('log')
ax4.set_yscale('log')
    
'''print(df_256)
print(df_128)
print(df_64)
print(df_32)'''

color = ['blue', 'limegreen', '#bc15b0', 'indigo']
linestyle = ["-", ":", "--", "-."]
plot_lines = ["A", "B", "C", "D"]
df_256.set_index('X').plot( style=linestyle,ax=ax1)
df_128.set_index('X').plot(style=linestyle,ax=ax2)
df_64.set_index('X').plot( style=linestyle,ax=ax3)
df_32.set_index('X').plot( style=linestyle,ax=ax4)
 
plt.show()

我做了一些閱讀並按如下方式解決了它。

import pandas as pd
import matplotlib.pyplot as plt
from matplotlib.gridspec import GridSpec

linestyle = ["-s", "-x", "-+", "o-"]
plot_lines = ["A", "B", "C", "D"]
X=[4,8,16,32,64,128,256,512,1024]
plot_title=['256MB','128MB','64MB','16MB','8MB', '4MB']

file_locn = ''r'C:\Users\me\Desktop\output.xlsx'''
df = pd.read_excel(file_locn, sheet_name='1', header=[0, 1])
df_256 = df.xs(256, axis=1, level=0)
df_128 = df.xs(128, axis=1, level=0)
df_64 = df.xs(64, axis=1, level=0)
df_32 = df.xs(32, axis=1, level=0)
df_16 = df.xs(64, axis=1, level=0)
df_8 = df.xs(32, axis=1, level=0)
df_4 = df.xs(4, axis=1, level=0)

nrow=2
ncol=3
df_list = [df_256, df_128, df_64, df_16, df_8, df_4]    
fig, axes = plt.subplots(nrow, ncol, sharex=True, sharey=True)
# plot counter
count=0
for c in range(ncol):
    df_list[count].set_axis('X')

plt.xscale('symlog',base=2)

count=0
axes[0,0].set_ylabel('Y-Axis label')
axes[1,0].set_ylabel('Y-Axis label')
axes[1,0].set_xlabel('X-Axis label')
axes[1,1].set_xlabel('X-Axis label')

for r in range(nrow):
    for c in range(ncol):
        df_list[count].set_index('X').plot(style=linestyle,ax=axes[r,c], legend=False)
        axes[r,c].set_title(plot_title[count])
        axes[r,c].set_xlim(4,1024)
        count+=1

lines, labels = fig.axes[-1].get_legend_handles_labels()    
fig.legend(lines, labels, loc='upper center',ncol=4)

plt.show()
