3.pyecharts饼图

一、适用条件
1、饼图：仅有一个要绘制的数据系列，没有负值，几乎没有零值，类别数目无限制,各类别分别代表整个饼图的一部分,
2、基础饼图、环形饼图、玫瑰图、环形玫瑰图、组合饼图
二、代码实现
1.导入所需包

from numpy.lib import index_tricks
from pyecharts import options as opts
from pyecharts.charts import  Pie
from pyecharts.commons.utils import JsCode
from pyecharts.globals import ThemeType
from pyecharts.render import make_snapshot
#from snapshot_phantomjs import snapshot
from snapshot_pyppeteer import snapshot
import pandas as pd
import numpy as np 

2.数据整理

###导入数据
df = pd.read_excel('picture.xlsx',sheet_name='pie')
###观察数据
print(df.head())
###选择所需数据
df_country = df.groupby(by = ["商家"]).sum().reset_index().sort_values(by = "销量",ascending= True) ###进行排序
x_list = list(df_country["商家"])
y_list = list(df_country["销量"])
title1 = "商家销量统计"
subtitle1 = "纯属虚构"
df_country1 = df_country.tail(3)
x1_list = list(df_country1["商家"])
y1_list = list(df_country1["销量"])
