plot 不同刻度不同轴 matplotlib

Question

我关注了其他一些类似的主题，但我无法让这件事工作我只想要两个不同的 y 轴（都在右边）和两个不同的 x 轴（一个自上而下）：

par2 = plt.gca()
par3 = par2.twinx()
par3 = par2.twiny()

par3.set_xlabel("Time (sentinel)")
par3.set_ylabel("Altitude")
par2.set_ylabel("snow_dz * snow_liq (kg/m²)")
par2.set_xlabel("Time (simu)")

color1 = plt.cm.viridis(0)
color2 = plt.cm.viridis(0.4)

p2, = par2.plot(good_date,sum_snow_layer,    color=color2, label="snow water equivalent")
p3, = par3.plot(snow_line,'r--',    color=color1, label="snow_line S2 GdesRousses")

#plt.xticks(times,  S2_dates_all, rotation=90)
#plt.yticks(alt_ticks, nniveaux, rotation=50)


lns = [p3, p2]
par3.legend(handles=lns, loc='upper left')



par2.spines['right'].set_position(('outward', 60)) 
par2.spines["right"].set_visible(True) 
par2.yaxis.set_label_position('right') 
par2.yaxis.set_ticks_position('right')
par2.xaxis.set_label_position('top') 
par2.xaxis.set_ticks_position('top')
par2.yaxis.label.set_color(p2.get_color())
par2.xaxis.label.set_color(p2.get_color())

par2.tick_params(axis='x', colors=color2)    #setting up X-axis tick color to red
par2.tick_params(axis='y', colors=color2)  #setting up Y-axis tick color to black
'''
par2.spines['left'].set_color('red')        # setting up Y-axis tick color to red
par2.spines['top'].set_color('red')         #setting up above X-axis tick color to red
#par2.xaxis.set_ticks(times,  S2_dates_all)  '''


par3.yaxis.set_label_position('right') 
#"par3.yaxis.tick_right()
par3.yaxis.label.set_color(p3.get_color())
par3.xaxis.label.set_color(p3.get_color())
par3.xaxis.set_label_position('bottom') 
par3.xaxis.set_ticks_position('bottom')
par3.tick_params(axis='x', colors=color1)    #setting up X-axis tick color to red
par3.tick_params(axis='y', colors=color1)  #setting up Y-axis tick color to black
#fig.tight_layout()

#plt.legend(bbox_to_anchor=(1.15, 1), loc=2, borderaxespad=0.)
plt.show()

正如你所看到的，一个很好，但另一个（紫色）在他的 y 轴上并不成功，我在 y 轴上看不到紫色......
