子图轴不合适

Question

我有这个代码：

import numpy as np
import matplotlib.pyplot as plt

x = np.genfromtxt("data1.dat")
y = np.genfromtxt("data2.dat")
z = np.genfromtxt("data3.dat")

fig, (ax1, ax2) = plt.subplots(2, 1, figsize=(7, 7))
fig.subplots_adjust(hspace=0.05)  # adjust space between axes
sc = ax1.scatter(x, y, c=[z])
sc= ax2.scatter(x, y, c=[z])

ax1.set_ylim(35, 45)  # outliers only
ax2.set_ylim(10, 15)  # most of the data

# hide the spines between ax and ax2
ax1.spines.bottom.set_visible(False)
ax2.spines.top.set_visible(False)
ax1.xaxis.tick_top()
ax1.tick_params(labeltop=False)  # don't put tick labels at the top
ax2.xaxis.tick_bottom()

d = .5  # proportion of vertical to horizontal extent of the slanted line
kwargs = dict(marker=[(-1, -d), (1, d)], markersize=12,
              linestyle="none", color='k', mec='k', mew=1, clip_on=False)
ax1.plot([0, 1], [0, 0], transform=ax1.transAxes, **kwargs)
ax2.plot([0, 1], [1, 1], transform=ax2.transAxes, **kwargs)

cbar_ax = fig.add_axes([0.95, 0.15, 0.025, 0.7]) #setting the colorbar
cbar = fig.colorbar(sc,cax=cbar_ax)
plt.show()

但是当我运行它时，当我 go 将图像导出为 a.png 时，彩条轴被切断

任何帮助将不胜感激 J
