前言

前面写过一篇用Python制作PPT的博客，感兴趣的可以参考

用Python制作PPT

这篇是关于用Python进行数据可视化的，准备作为一个长贴，随时更新有价值的Python可视化用例,都是网上搜集来的，与君共享,本文所有测试均基于Python3.

首先搭建环境

$pip install pyecharts -U
$pip install echarts-themes-pypkg
$pip install snapshot_selenium
$pip install echarts-countries-pypkg
$pip install echarts-cities-pypkg
$pip install echarts-china-provinces-pypkg
$pip install echarts-china-cities-pypkg
$pip install echarts-china-counties-pypkg
$pip install echarts-china-misc-pypkg
$pip install echarts-united-kingdom-pypkg
$pip install -i https://pypi.tuna.tsinghua.edu.cn/simple pyecharts
$git clone https://github.com/pyecharts/pyecharts.git
$cd pyecharts/
$pip install -r requirements.txt
$python setup.py install
 

一顿操作下来，该装的不该装的都装上了，多装一些包没坏处，说不定哪天就用上了呢

实例代码

例子1：

from pyecharts.charts import Bar
from pyecharts import options as opts

bar = (
    Bar()
    .add_xaxis(["chenshan", "maoyi", "longdai", "kuzi", "fengyi", "gaogenxie", "wazi"])
    .add_yaxis("storeA", [114, 55, 27, 101, 125, 27, 105])
    .add_yaxis("storeB", [57, 134, 137, 129, 145, 60, 49])
    .set_global_opts(title_opts=opts.TitleOpts(title="sales"))
)
#bar.render_notebook()
bar.render()

render():默认将会在根目录下生成一个 render.html 的文件，支持 path 参数，设置文件保存位置，如 render("./xx/xxx.html").

结果是以网页的形式输出的，执行后，在当前目录下生成render.html，用浏览器打开,最好事先安装chrome浏览器.

例子2：

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()

例子3:

import pyecharts.options as opts
from pyecharts.charts import Line
from pyecharts.faker import Faker

c = (
    Line()
    .add_xaxis(Faker.choose())
    .add_yaxis("storeA", Faker.values(), is_smooth=True)
    .add_yaxis("storeB", Faker.values(), is_smooth=True)
    .set_global_opts(title_opts=opts.TitleOpts(title="Line-smooth"))
)
c.render()

例子4:

    [2309.16, 2286.6, 2264.83, 2333.29],
