python绘图pyecharts+pandas的使用详解

pyecharts介绍

pyecharts 是一个用于生成 Echarts 图表的类库。Echarts 是百度开源的一个数据可视化 JS 库。用 Echarts 生成的图可视化效果非常棒

为避免绘制缺漏，建议全部安装

为了避免下载缓慢，作者全部使用镜像源下载过了

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple/ echarts-countries-pypkg

基础案例

from pyecharts.charts import Bar
bar = Bar()
bar.add_xaxis(['小嘉','小琪','大嘉琪','小嘉琪'])
bar.add_yaxis('得票数',[60,60,70,100])
#render会生成本地HTML文件，默认在当前目录生成render.html
# bar.render()
#可以传入路径参数，如 bar.render("mycharts.html")
#可以将图形在jupyter中输出，如 bar.render_notebook()
bar.render_notebook()

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

# 示例数据

# 1.x版本支持链式调用
bar = (Bar()
    .add_xaxis(cate)
    .add_yaxis('渠道', data1)
    .add_yaxis('门店', data2)
    .set_global_opts(title_opts=opts.TitleOpts(title="示例", subtitle="副标"))
   )
bar.render_notebook()

    .set_global_opts(title_opts=opts.TitleOpts(title="Line-基本示例", subtitle="我是副标题"))
   )

line.render_notebook()

from pyecharts import options as opts
from pyecharts.charts import Geo
from pyecharts.globals import ChartType
import random

    .add_schema(maptype="福建")
    .add("门店数", data,

geo.render_notebook()

啊哈这个还访问不了哈

20200822pyecharts+pandas 初步学习

作者今天学习做数据分析，有错误请指出
下面贴出源代码

# 获取数据

}
#获取json数据
response = requests.get(url=china_url,headers=headers).json()

print(response)
#先将json数据转 python的字典
data = json.loads(response['data'])

#保存数据 这里使用encoding='utf-8' 是因为作者想在jupyter上面看
with open('./国内疫情.json','w',encoding='utf-8') as f:
  #再将python的字典转json数据
  # json默认中文以ASCII码显示 在这里我们以中文显示 所以False
  #indent=2：开头空格2 

  f.write(json.dumps(data,ensure_ascii=False,indent=2))

转换为json格式输出的文件

#删除total列 在原有的数据基础

# 将其保存到excel中
from openpyxl import load_workbook

作者这边还有国外的，不过没打算分享出来，大家就看看，总的来说我们国内情况还是非常良好的
