正如我在这里回答的，你可以通过样式设置(样式表或rcParams)从所有的图中删除棘线:

import matplotlib as mpl

mpl.rcParams['axes.spines.left'] = False
mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
mpl.rcParams['axes.spines.bottom'] = False

plt.axis('off')
plt.savefig(file_path, bbox_inches="tight", pad_inches = 0)

plt。Savefig本身有这些选项，只需要在之前设置轴

df = pd.DataFrame({
'client_scripting_ms' : client_scripting_ms,
 'apimlayer' : apimlayer, 'server' : server
}, index = index)

ax = df.plot(kind = 'barh', 
     stacked = True,
     title = "Chart",
     width = 0.20, 
     align='center', 
     figsize=(7,5))

plt.legend(loc='upper right', frameon=True)

ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('right')

这里有另一个解决方案:

img = io.imread(crt_path)

fig = plt.figure()
fig.set_size_inches(img.shape[1]/img.shape[0], 1, forward=False) # normalize the initial size
ax = plt.Axes(fig, [0., 0., 1., 1.]) # remove the edges
ax.set_axis_off() # remove the axis
fig.add_axes(ax)

ax.imshow(img)

plt.savefig(file_name+'.png', dpi=img.shape[0]) # de-normalize to retrieve the original size

我过去常常这样做:

from pylab import *
axes(frameon = 0)
...
show()

plt.box(False)
plt.xticks([])
plt.yticks([])
plt.savefig('fig.png')

应该能行。
