您可以尝试更改图形尺寸，xticklabel的尺寸，其旋转角度等.

You can try changing the figure size, the size of the xticklabels, their angle of rotation, etc.

# Set the figure size
fig = plt.figure(1, [20, 8])

# Set the x-axis limit
ax.set_xlim(-1,100)
# Change of fontsize and angle of xticklabels
plt.setp(ax.get_xticklabels(), fontsize=10, rotation='vertical')
