在python中绘制直方图

Question

我用下面的代码计算了两个值

with open('paths_finished.tsv', 'rb') as tsvfile:
total = 0
count = 0
total2 = 0
count2 = 0
t = 0
for line in tsvfile:

   if '<;' in line:
        total += line.count(';')
        t += line.count('<;')
        count +=+1
   else:
        total2 += line.count(';') 
        count2 += 1

humanaverage = (total-t) / float(count)
computeraverage = total2 / float(count2)

print humanaverage

print computeraverage

输出：

8.33285158421

4.72252533125

如何在直方图中绘制这两个值？

Answer 1

你可以使用 bar:

bar([0,1],[8.33285158421,4.72252533125],width=1)
xticks([0.5,1.5],['humanaverage','computeraverage'])
