一.基本概念

class pyecharts.charts.Pie

class Pie(
    # 初始化配置项，参考 `global_options.InitOpts`
    init_opts: opts.InitOpts = opts.InitOpts()
)

func pyecharts.charts.Pie.add

def add(
    # 系列名称，用于 tooltip 的显示，legend 的图例筛选。
    series_name: str,

    # 系列数据项，格式为 [(key1, value1), (key2, value2)]
    data_pair: Sequence,

    # 系列 label 颜色
    color: Optional[str] = None,

    # 饼图的半径，数组的第一项是内半径，第二项是外半径
    # 默认设置成百分比，相对于容器高宽中较小的一项的一半
    radius: Optional[Sequence] = None,

    # 饼图的中心（圆心）坐标，数组的第一项是横坐标，第二项是纵坐标
    # 默认设置成百分比，设置成百分比时第一项是相对于容器宽度，第二项是相对于容器高度
    center: Optional[Sequence] = None,

    # 是否展示成南丁格尔图，通过半径区分数据大小，有'radius'和'area'两种模式。
    # radius：扇区圆心角展现数据的百分比，半径展现数据的大小
    # area：所有扇区圆心角相同，仅通过半径展现数据大小
    rosetype: Optional[str] = None,

    # 饼图的扇区是否是顺时针排布。
    is_clockwise: bool = True,

    # 标签配置项，参考 `series_options.LabelOpts`
    label_opts: Union[opts.LabelOpts, dict] = opts.LabelOpts(),

    # 提示框组件配置项，参考 `series_options.TooltipOpts`
    tooltip_opts: Union[opts.TooltipOpts, dict, None] = None,

    # 图元样式配置项，参考 `series_options.ItemStyleOpts`
    itemstyle_opts: Union[opts.ItemStyleOpts, dict, None] = None,

    # 可以定义 data 的哪个维度被编码成什么。
    encode: types.Union[types.JSFunc, dict, None] = None,
)

数据具体处理过程链接：去哪儿

1.数据处理与获取

import pandas as pd

data=pd.read_csv("travel2.csv")

import re

def Look(e):
    
    if '万' in e:
        num=re.findall('(.*?)万',e)
        return float(num[0])*10000
    else:
        return float(e)
    
data['浏览次数']=data['浏览量'].apply(Look)
data.drop(['浏览量'],axis=1,inplace=True)
data['浏览次数']=data['浏览次数'].astype(int)

data1=data.head(7)
data.head(7)

datas=[list(z) for z in zip(data1["地点"].tolist(),data1["浏览次数"].tolist())]
datas.sort(key=lambda x:x[1])
datas

[['AguadePau', 261],
 ['阿联酋', 3860],
 ['建水', 6176],
 ['婺源', 9055],
 ['日本', 12000],
 ['敦煌', 14000],
 ['海宁', 22000]]
