我需要使这些2x2子图为正方形，同时仍使它们共享同一轴，并且不更改轴范围。我真的不想不必要地移动图例或更改轴范围。

这是我的代码：

fig,((ax1,ax2),(ax3,ax4)) = plt.pyplot.subplots(2,2,sharex = True)
fig.subplots_adjust(hspace=0,wspace = 0)
plt.pyplot.subplots_adjust(right=.8,top=.8)
ax1.grid()
ax2.grid()
ax3.grid()
ax4.grid()
ax1.scatter(p1,q1,marker = 's',color = 'royalblue',alpha = 0.5,label = 'Saintonage et al. 2017')
ax1.scatter(p33,q33,color = 'rebeccapurple',alpha = 0.5)
ax3.grid()
ax1.plot(x000,func6(x000),color ='k')
ax1.xaxis.grid(True,which='minor')
ax2.xaxis.grid(True,which='minor')
ax3.xaxis.grid(True,which='minor')
ax4.xaxis.grid(True,which='minor')
ax1.scatter(p2,q2,color = 'seagreen',label = 'Saintonage et al. 2017')
ax1.scatter(p3,q3,marker ='s',color = 'maroon',label = 'Saintonage et al. 2017')
ax1.set_ylim([-1.2,2.2])
ax2.scatter(p4,q4,marker = 'o',alpha = 0.75)
ax2.scatter(p30,q30,alpha = 0.75)
ax2.plot(x0,func1(x0),color ='k')
ax2.scatter(p5,q5,alpha = 0.75)
ax2.set_ylim([-1.2,2.2])
ax2.set_xlim([9.8,11.7])
ax3.scatter(p7,q7,marker = 'D',alpha = 0.75)
ax3.plot(x00,func2(x00),color = 'k')
upperlimit = np.array([1],dtype = bool)
ax4.scatter(lmassg,lsfrg,marker = 'd',color = 'maroon')  
ax3.set_ylim([0,3.5])
ax4.plot(x000,func(x000),color ='k')
ax4.set_ylim([0,3.5])
fig.legend(handles = legend_elements,numpoints = 1,loc = (.77,.3),ncol=1,fontsize = 8 )
ax1.tick_params(axis='both',labelsize=10)
ax1.tick_params(axis='both',labelsize=12)
ax2.tick_params(axis='both',labelsize=10)
ax2.tick_params(axis='both',labelsize=2)
ax3.tick_params(axis='both',labelsize=12)
ax3.tick_params(axis='both',labelsize=12)
ax4.tick_params(axis='both',labelsize=12)
ax4.tick_params(axis='y',labelsize=2)

这是我的情节：
