pyecharts操作一

pyecharts 是一个用于生成Echarts图表的Python库。Echarts是百度开源的一个数据可视化JS库，可以生成一些非常酷炫的图表。

• 环境安装

  • pip install pyecharts

• 检查版本

import pyecharts
print(pyecharts.version)
2.0.3

• 柱状图绘制

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

#v1版本开始支持链式调用
bar = (Bar(init_opts = opts.InitOpts(theme = ThemeType.WESTEROS))
.add_xaxis([“Apple”,“Huawei”,“Xiaomi”,“Oppo”,“Vivo”,“Meizu”]) #指定x轴
#可以指定多个y轴
.add_yaxis(“电商渠道”,[133,163,99,117,108,33])
.add_yaxis(“门店”,[66,87,103,78,55,77])
#全局配置操作
.set_global_opts(title_opts=opts.TitleOpts(title=“Bar-基本示例”,subtitle=“我是副标题”))
)
#在juputer notebook中渲染
bar.render_notebook()

• 添加工具箱配置
  • 在全局配置set_global_opts中添加：
    • toolbox_opts=opts.ToolboxOpts()

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

#示例数据
cate = [‘Apple’,‘Huawei’,‘Xiaomi’,‘Oppo’,‘Vivo’,‘Meizu’]
data1 = [133,163,99,117,108,33]
data2 = [66,87,103,78,55,77]

#1.x版本支持链式调用
bar = (Bar()
.add_xaxis(cate) #指定x轴
#可以指定多个y轴
.add_yaxis(‘电商渠道’,data1)
.add_yaxis(‘门店’,data2)
.set_global_opts(title_opts=opts.TitleOpts(title=“Bar-基本示例”,subtitle=“我是副标题”)
,toolbox_opts=opts.ToolboxOpts() #添加工具箱代码
)
)
#在jupyter notebook中渲染
bar.render_notebook()

• 饼图绘制

cate = [‘Apple’, ‘Huawei’, ‘Xiaomi’, ‘Oppo’, ‘Vivo’, ‘Meizu’]
data = [163, 134, 117, 109, 99, 56]

[list(z) for z in zip(cate,data)]

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

#示例数据
cate = [‘Apple’, ‘Huawei’, ‘Xiaomi’, ‘Oppo’, ‘Vivo’, ‘Meizu’]
data = [163, 134, 117, 109, 99, 56]

pie = (Pie()
.add(‘’,[list(z) for z in zip(cate,data)],
radius=[“30%”,“75%”], #设置半径（内外圈半径）
rosetype=“radius” #半径形式的玫瑰型样式（经典）
)
.set_global_opts(title_opts=opts.TitleOpts(title=“Pie-基本示例”,subtitle=“我是副标题”))
.set_series_opts(label_opts=opts.LabelOpts(formatter=“{b}:{d}%”))
)

pie.render_notebook()

• 折线图

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

#示例数据
cate = [‘Apple’, ‘Huawei’, ‘Xiaomi’, ‘Oppo’, ‘Vivo’, ‘Meizu’]
data1 = [133,163,99,117,108,33]
data2 = [66,87,103,78,55,77]

“”"
折线图示例:

1. is_smooth 折线 OR 平滑
2. markline_opts 标记线 OR 标记点
   “”"
   line = (Line()
   .add_xaxis(cate)
   .add_yaxis(‘电商渠道’,data1,
   #均值标记线
   markline_opts=opts.MarkLineOpts(data=[opts.MarkAreaItem(type_=“average”)]))
   .add_yaxis(‘门店’,data2,
   is_smooth=True,
   markline_opts=opts.MarkLineOpts(data=[opts.MarkLineItem(type_=“average”)])
   )
   .set_global_opts(title_opts=opts.TitleOpts(title=“Line-基本示例”,subtitle=“我是副标题”))
   )

line.render_notebook()

• 漏斗图

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

示例数据

cate = [‘访问’, ‘注册’, ‘加入购物车’, ‘提交订单’, ‘付款成功’]
data = [30408, 15240, 10055, 8119, 5708]

“”"
漏斗图示例：

1. sort_控制排序，默认降序；
2. label_opts标签显示位置
   “”"
   funnel = (Funnel()
   .add(“用户数”,[list(z) for z in zip(cate,data)],
   sort_=‘ascending’,
   label_opts=opts.LabelOpts(position=“inside”)
   )
   .set_global_opts(title_opts=opts.TitleOpts(title=“Funnel-基本示例”,subtitle=“我是副标题”))
   )

funnel.render_notebook()

.add(
maptype=“world”,
series_name=“World Population”,
data_pair=POPULATION[1:],
is_map_symbol_show=False,
label_opts=opts.LabelOpts(is_show=False),
