【问题描述】:
我有一本字典:
{'DATE': 65,
'ORG': 93,
'PERSON': 62,
'GPE': 18,
'PRODUCT': 18,
'FAC': 4,
'CARDINAL': 50,
'ORDINAL': 15,
'NORP': 10,
'MONEY': 3,
'PERCENT': 2,
'TIME': 5,
'LOC': 5,
'QUANTITY': 2}
我只想将它绘制在饼图中,显示这些项目的百分比分布。这个怎么画???
我在这里尝试过解决方案:Trying to create a pie and bar chart from the data below
所以我使用了那里发布的代码作为解决方案:
amount_of_TP_ner_tags # this is the dictionary I want to plot. see above
# dont use values inside a list as column values for a dataframe
browser2 = {}
[browser2.update({key : val[0]}) for key, val in amount_of_TP_ner_tags.items()]
x = pd.Series(browser2)
y = pd.Series.sort_values(x)
z = pd.DataFrame(y)
fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(8,4))
# you need to specify which column of the dataframe you want to plot (here 0)
z.plot(y=0, kind = 'pie', ax = axes[0])
z.plot(kind = 'bar', ax = axes[1])
axes[0].set_aspect("equal") # make aspect equal (such that circle is not eliptic)
#place the legend at a decent position
axes[0].legend(loc=1, bbox_to_anchor= (1,0.2), fontsize=11)
plt.tight_layout()
plt.show()
但我收到一条错误消息:
TypeError Traceback (most recent call last)
<ipython-input-258-7ca72d2d0ca4> in <module>
1 # dont use values inside a list as column values for a dataframe
2 browser2 = {}
----> 3 [browser2.update({key : val[0]}) for key, val in amount_of_TP_ner_tags.items()]
4
5 x = pd.Series(browser2)
<ipython-input-258-7ca72d2d0ca4> in <listcomp>(.0)
1 # dont use values inside a list as column values for a dataframe
2 browser2 = {}
----> 3 [browser2.update({key : val[0]}) for key, val in amount_of_TP_ner_tags.items()]
4
5 x = pd.Series(browser2)
TypeError: 'int' object is not subscriptable
那么我该如何绘制呢?
