matplotlib图插入空白

Question

I'm making a figure for that includes an inset. I cannot figure out how to get the whitespace on to be removed. I've tried using tight_sublot() but it still leaves whitespace near the inset that I'd like to remove. Any suggestions?

import numpy as np
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import silicon2_data

data = silicon2_data.out

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

for temperature in data:
    xs = temperature[:,0]
    ys = temperature[:,1]
    zs = temperature[:,2]
    ax.scatter(xs, ys, zs)
ax.set_zbound(0, 1.4)

ax.set_xlabel(r'$2\theta$ (degrees)')
ax.set_ylabel('Temperature (K)')
ax.set_zlabel(r'Intensity ($10^5$cts/sec)')
#inset
ax2 = fig.add_axes([0.15, 0.62, 0.25, 0.25])

ax2.plot(data[3,:,0], data[3,:,2],'bo')
ax2.plot(data[7,:,0], data[7,:,2],'rx')

ax2.legend(('16K', '18K'), loc=0, fontsize ='small')
ax2.set_ybound(0, 1.4)

plt.tight_layout()
plt.show()

This is roughly what I'm trying to make:

After calling

fig = plt.figure()

you can adjust characteristics of the subplots before adding them with fig.add_subplot() by using pyplot's subplots_adjust() method. For your purposes, you might try

fig.subplots_adjust(wspace=0.05)
fig.subplots_adjust(hspace=0.05)

where the number is the fraction of the figure's width or height.
