matplotlib shared axis implementation (X or Y axis)

（nrows = 1，ncols = 1，sharex = False，sharey = False，
squeeze = True，subplot_kw =not have，gridspec_kw =not have，** fig_kw ）

'''
1. Purpose of the program:
   Based on sharex and sharey to implement
     (1) Share x-axis
     (2) Share y-axis
     (3) Share both x-axis and y-axis at the same time
     (4) Adjusting the distance between subplots

2. Versions
   2.1 Qingdao, Shandong May 18, 2021 Version 1
