1.显现用到的包
Pyecharts 是一个用于生成 Echarts 图表的类库。常规的Echarts 是由百度开源的一个数据可视化 JS 库，主要用于数据可视化。简单来说，Pyecharts是一款将python与echarts结合的强大的数据可视化工具。
使用 Pyecharts 可以生成独立的网页，也可以在 flask , Django 中集成使用。

2.Pyecharts安装
# 安装 v1 以上版本
$ pip install pyecharts -U
# 如果需要安装 0.5.11 版本的开发者，可以使用
# pip install pyecharts==0.5.11
PS: 这里要专门说明一下，自从 0.3.2 开始，为了缩减项目本身的体积以及维持 pyecharts 项目的轻量化运行，pyecharts 将不再自带地图 js 文件。如用户需要用到地图图表（Geo、Map），可自行安装对应的地图文件包。
# 通过pip命令进行安装
pip install echarts-countries-pypkg
pip install echarts-china-provinces-pypkg
pip install echarts-china-cities-pypkg
3.实践
1.柱状图
from pyecharts.charts import Bar
from pyecharts import options as opts
# V1 版本开始支持链式调用
bar = (
Bar()
.add_xaxis(["衬衫", "毛衣", "领带", "裤子", "风衣", "高跟鞋", "袜子"])
.add_yaxis("商家A", [114, 55, 27, 101, 125, 27, 105])
.add_yaxis("商家B", [57, 134, 137, 129, 145, 60, 49])
.set_global_opts(title_opts=opts.TitleOpts(title="某商场销售情况"))
)
bar.render()

2.Pie饼状图
from pyecharts import options as opts
from pyecharts.charts import Pie
from pyecharts.faker import Faker
pie = (
Pie()
.add("", [list(z) for z in zip(Faker.choose(), Faker.values())])
.set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"])
.set_global_opts(title_opts=opts.TitleOpts(title="Pie-设置颜色"))
.set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}"))
)
pie.render()

from pyecharts.charts import Gauge
g = (
Gauge()
.add("", [("完成率", 99.6)])

g.render()
