1.概述
pyecharts 是百度开源的，适用于数据可视化的工具，配置灵活，展示图表相对美观，顺滑。
2.安装
python3环境下的安装：
pip3 install pyecharts3.数据可视化代码
3.1 柱状图
from pyecharts import options as opts
from pyecharts.charts import Bar
from pyecharts.faker import Faker
c = (
Bar()
.add_xaxis(Faker.choose())
.add_yaxis("商家A", Faker.values(), stack="stack1")
.add_yaxis("商家B", Faker.values(), stack="stack1")
.set_series_opts(label_opts=opts.LabelOpts(is_show=False))
.set_global_opts(title_opts=opts.TitleOpts(title="Bar-堆叠数据（全部）"))
.render("bar_stack0.html")
)执行上述代码，会在相对目录生成mycharts.html文件，通过页面打开。
3.2 折线图

)
.set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}"))
.render("pie_radius.html")
)
