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()

4. 仪表盘

from pyecharts import options as opts

from pyecharts.charts import Gauge

g = (

Gauge()

.add("", [("完成率", 99.6)])

.set_global_opts(title_opts=opts.TitleOpts(title="Gauge-基本示例"))

)

g.render()

5.折线图

import pyecharts.options as opts

from pyecharts.charts import Line

from pyecharts.faker import Faker

c = (

Line()

.add_xaxis(Faker.choose())

.add_yaxis("商家A", Faker.values(), is_smooth=True)

.add_yaxis("商家B", Faker.values(), is_smooth=True)

.set_global_opts(title_opts=opts.TitleOpts(title="Line-smooth"))

)

c.render()
