How to invert y axis in subplot Python-CodePudding

I am trying to make a subplot of three figures. All of the figures should have inverted y-axes. But when I use ´gca().invert_yaxis()´ it only inverts the last of the three subplots and not the first two. How can I invert all of the y axes?

import matplotlib.pyplot as plt
import pandas
import numpy as np

# Create the subplot
axes,(p1,p2, p3) = plt.subplots(1, 3)

# Temperature proxies
p1.plot(Ti/Mg, xrf_depth) 
p1.set_title("Clastic influx (Ti/Mg) and Ti (ppm)")
plt.gca().invert_yaxis()

p2.plot(Ti/1000, xrf_depth)
ax = plt.gca()


p3.plot(Ca/Si, xrf_depth, '-g')
p3.set_title("Primary production (Ca/Si")


plt.show()

CodePudding user response：

plt.gca() literally means "get current axes", so it makes sense that only the last one is affected. In your case, the three axes are p1,p2, p3, therefore p1.invert_yaxis() etc. should do the job. Delete all lines containing gca() in your code.
