这是我最后使用的代码。它不再是最小的了。也许它有帮助。
import matplotlib.pyplot as plt
import numpy as np
def adjust_spines(ax,spines):
for loc, spine in ax.spines.items():
if loc in spines:
spine.set_smart_bounds(True)
else:
spine.set_color('none') # don't draw spine
# turn off ticks where there is no spine
if 'left' in spines:
ax.yaxis.set_ticks_position('left')
else:
# no yaxis ticks
ax.yaxis.set_ticks([])
def nbar(samples, data, err, bWidth=0.4, bSafe=True, svgName='out'):
fig,a = plt.subplots(frameon=False)
if len(data)!=len(samples):
print("length(data) must be equal to length(samples)!")
return
ticks = np.arange(len(data))
p1 = plt.bar(ticks, data, bWidth, yerr=err)
plt.xticks(ticks+bWidth/2., samples )
adjust_spines(a,['bottom'])
a.xaxis.tick_bottom()
if bSafe:
fig.savefig(svgName+".svg")
samples = ('Sample1', 'Sample2','Sample3')
qyss = (91, 44, 59)
qysserr = (1,5,4)
nbar(samples,qyss,qysserr,svgName="test")
