Before Change

v = plt.axis()
plt.contour(Z, levels, colors="k", origin="image", extent=extent)
plt.axis(v)
ylim = plt.get(plt.gca(), "ylim")
plt.setp(plt.gca(), ylim=ylim[::-1])
plt.title("Origin from rc, reversed y-axis")
plt.colorbar(im)

plt.tight_layout()

After Change

// We are making a thick green line as a zero contour.
// Specify the zero level as a tuple with only 0 in it.

cset3 = axs[0].contour(X, Y, Z, (0,), colors="g", linewidths=2)
axs[0].set_title("Filled contours")
fig.colorbar(cset1, ax=axs[0])
