自学教程:利用Python进行数据可视化的实例代码

这篇教程利用Python进行数据可视化的实例代码写得很实用,希望能帮到您。

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 Barfrom 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 optsfrom pyecharts.charts import Piefrom 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 optsfrom pyecharts.charts import Linefrom 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()
