Matplotlib: keep grid lines behind the graph but the y and x axis above

Question

I am having a hard time plotting grid lines under my graphs without messing with the main x and y axis zorder:

import matplotlib.pyplot as plt
import numpy a         


        

Answer 1

A easier and better solution is to copy the lines from the grid command and disable the grid and again add the lines again but with correct zorder:

ax.grid(True)
lines = ax.xaxis.get_gridlines().copy() + ax.yaxis.get_gridlines().copy()
ax.grid(False)
for l in lines:
    ax.add_line(l)
    l.set_zorder(0)
