python - matplotlib figure inset whitespace -

-

i'm making figure includes inset. cannot figure out how whitespace on removed. i've tried using tight_sublot() still leaves whitespace near inset i'd remove. suggestions?

import numpy np mpl_toolkits.mplot3d import axes3d import matplotlib.pyplot plt import silicon2_data  data = silicon2_data.out  fig = plt.figure() ax = fig.add_subplot(111, projection='3d')  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 i'm trying make:

enter image description here

after calling 

fig = plt.figure()

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

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

where number fraction of figure's width or height.
