我是初学者,matplotlib我正在尝试绘制两个条形图。对于第二个图,xlabels 很好,但对于第一个图,我得到了 xlabels 作为列表,它也有 unicode 字符串格式。这是我的代码:
def get_val_from_dict(objects, n):
x = []
y = []
for k,v in objects.items():
probalities = float(v)/n
cat = k
x.append(cat)
y.append(probalities)
return x,y
my x,y列表具有以下两个数据文件的格式:
[u'fast_food', u'school', u'bar', u'beauty', u'hairdresser', u'park', u'hotel', u'kiosk', u'pub', u'nightclub', u'supermarket', u'restaurant', u'bakery', u'pharmacy', u'doctors', u'fitness_centre', u'cafe', u'bank', u'clothes']
[0.08, 0.03, 0.03, 0.01, 0.05, 0.03, 0.19, 0.12, 0.04, 0.01, 0.01, 0.25, 0.03, 0.01, 0.02, 0.02, 0.05, 0.01, 0.02]
[u'fast_food', u'school', u'bar', u'jewelry', u'beauty', u'hairdresser', u'shoes', u'park', u'museum', u'restaurant', u'kiosk', u'supermarket', u'pharmacy', u'bakery', u'greengrocer', u'cafe', u'bank', u'clothes']
[0.03, 0.03, 0.03, 0.03, 0.03, 0.15, 0.03, 0.09, 0.03, 0.21, 0.06, 0.03, 0.03, 0.06, 0.03, 0.06, 0.06, 0.03]
x_all = []
y_all = []
name_ = []
for arg in sys.argv[1:]:
reload(sys)
sys.setdefaultencoding('utf-8')
fp = open(arg)
contents = fp.read()
name = arg
n, data = subsamples(contents)
x, y = get_val_from_dict(data, n)
x_all.append(x)
y_all.append(y)
name_.append(name)
count=0
for i in range(len(x_all)):
count += 1
f, axarr = plt.subplots(count, sharex='col', sharey='row')
for i in range(len(x_all)):
axarr[i].set_title(label ="%s" %(name_[i]))
axarr[i].bar(x_all[i], y_all[i])
axarr[i].tick_params(axis='both', which='both')
axarr[i].set_xlabel(x)
axarr[i].set_xticklabels(x_all[i], rotation=90)
plt.show()
如何将第一个子图绘制为下面的图?
