如何使文本出现在 Matplotlib 中的 3barplot 之后

Question

Why doesn't zorder work in this case? I've tried using it but the text still ends up being covered by the bar plot towers.

import numpy as np
from matplotlib import pyplot as plt

Percentage_Differences_1 = np.array([ [7.94*(10**-10),7.94*(10**-9),7.94*(10**-8),7.94*(10**-7),7.94*(10**-6),7.94*(10**-5)],
                                [7.92*(10**-12),7.92*(10**-11),7.92*(10**-10),7.92*(10**-9),7.92*(10**-8),7.92*(10**-7)],
                                [7.72*(10**-14),7.72*(10**-13),7.72*(10**-12),7.72*(10**-11),7.72*(10**-10),7.72*(10**-9)],
                                [5.66*(10**-16),5.66*(10**-15),5.66*(10**-14),5.66*(10**-13),5.66*(10**-12),5.66*(10**-11)],
                                [1.49*(10**-17),1.49*(10**-16),1.49*(10**-15),1.49*(10**-14),1.49*(10**-13),1.49*(10**-12)],
                                [2.21*(10**-18),2.21*(10**-17),2.21*(10**-16),2.21*(10**-15),2.21*(10**-14),2.21*(10**-13)] ]) # Layer 1, 12

fig1 = plt.figure(dpi = 120, tight_layout = True)
fig1.set_size_inches(10, 7)

ax1 = fig1.add_subplot(111, projection='3d')

width = depth = 0.3

column_names = ['$10^{-6} m$','$10^{-5} m$','$10^{-4} m$','$10^{-3} m$','$10^{-2} m$','$10^{-1} m$']
row_names = ['$10^{-6} g$','$10^{-5} g$','$10^{-4} g$','$10^{-3} g$','$10^{-2} g$','$10^{-1} g$']
height_names = ['$10^{-2}$','$10^{-4}$','$10^{-6}$','$10^{-8}$','$10^{-10}$','$10^{-12}$','$10^{-14}$','$10^{-16}$','$10^{-18}$']

for x in range(0,6):
    for y in range(0,6):
        plot1 = ax1.bar3d(x, y, 0, width, depth, np.log10(Percentage_Differences_1[x][y]), color = "#0040bf", alpha=0.3, zorder = 1)
        txt1 = ax1.text(x,y,1.15*np.log10(Percentage_Differences_1[x][y]),'{:.2e}'.format(Percentage_Differences_1[y][x]), verticalalignment='top', bbox=dict(facecolor='grey', alpha=0.5), zorder = 2)
        
ax1.view_init(-140, -30)

ax1.set_xticks(np.linspace(0, 6, num = 6))
ax1.set_yticks(np.linspace(0, 6, num = 6))
ax1.set_xticklabels(column_names)
ax1.set_yticklabels(row_names)
ax1.set_zticklabels(height_names)
ax1.set_xlabel("Mass", labelpad = 13, rotation = 45)
ax1.set_ylabel("Radius", labelpad = 10, rotation = 45)
ax1.set_zlabel("Deviation $\Delta$")
ax1.set_title("1st Initial Condition: $r(0)$ and $r'(0)$ of $\Theta(12) = 2.18 \\times 10^{7} m$", pad = 40)

plt.show()

I've tried using both set_zorder and zorder but the plot still ends up covering the majority of the text labels.

Change your zorder for a number larger than the number of bar objects, 100 for example:
