分享一些python-pyecharts作图小技巧,用于展示汇报。
一、特点
# 安装
pip install pyecharts
from pyecharts import options as opts #全局配置
from pyecharts.globals import ThemeType # 主题
chart.render('idx_name_Completion%.html') #保存为网页,可进一步嵌入到ppt
chart.render_notebook() #直接查看结果
二、常用图形
(1)漏斗图
功能:用于呈现不同阶段数据流变化的情况
示例代码:
from pyecharts.charts import Funnel
x=['visit','shoppingcar','order','pay','done']
y=[1000,890,500,300,280]
data=[i for i in zip(x,y)]
chart=Funnel()
chart.add(series_name='headcount'
,data_pair=data
,sort_='ascending',gap=15
,label_opts=opts.LabelOpts(is_show=True,position='inside')
,tooltip_opts=opts.TooltipOpts(trigger='item',formatter='{a}:{c}')
)
chart.set_global_opts(
title_opts=opts.TitleOpts(title='e_buy_funnle',pos_left='left')
,legend_opts=opts.LegendOpts(is_show=False)
)
chart.render('e_buy_funnle.html')
(2)散点图(带有涟漪效果)
功能:同时比较2个指标的数据比较
示例代码:
from pyecharts.charts import EffectScatter
x=[28,16,34,25,35,46,20,40] # data['x'].tolist()
y=[45,25,78,46,18,35,94,27] # data['y'].tolist()
chart=EffectScatter()
chart.add_xaxis(x)
chart.add_yaxis(
series_name='age,shopping($)'
,y_axis=y
,label_opts=opts.LabelOpts(is_show=False)
,symbol_size=15
)
chart.set_global_opts(
title_opts=opts.TitleOpts(title='salse-scatter')
,yaxis_opts=opts.AxisOpts(type_='value',name='shopping($)',name_location='middle',name_gap=40)
,xaxis_opts=opts.AxisOpts(type_='value',name='age',name_location='middle',name_gap=40)
,tooltip_opts=opts.TooltipOpts(trigger='item',formatter='{a}:{c}')
)
chart.render('lianyi-scatter.html')
(3)水球图
功能:适用于展示单个或多个百分数
示例代码:
from pyecharts.charts import Liquid
a=68
t=100
chart=Liquid()
chart.add(
series_name='productA'
,data=[a/t]
,shape='circle' # 改变形状,如圆形、矩形rect、箭头pin等
)
chart.set_global_opts(
title_opts=opts.TitleOpts(title='sales',pos_left='center')
)
chart.render('sales.html')
from pyecharts.charts import Liquid
a=68
b=120
c=37
t=100
chart=Liquid()
chart.set_global_opts(
title_opts=opts.TitleOpts(title='sales',pos_left='center')
)
chart.add(
series_name='productA'
,data=[a/t]
,center=['20%','50%'] # 指定水球中心点在图表中的位置
)
chart.add(
series_name='productB'
,data=[b/t]
,center=['50%','50%']
)
chart.add(
series_name='productC'
,data=[c/t]
,center=['80%','50%']
)
chart.render('sales-2.html')
(4)仪表盘
功能:适用于展示单个或多个百分比
示例代码:
from pyecharts.charts import Gauge
chart=Gauge()
chart.add(
series_name='idx_name'
,data_pair=[('Completion%','62.25')]
,split_number=10 #平均分割段数
,radius='50%' # 设置仪表盘半径
,title_label_opts=opts.LabelOpts(font_size=20,color='red',font_family='Microsoft YaHei')
)
chart.set_global_opts(
tooltip_opts=opts.TooltipOpts(is_show=True,formatter='{a}
{b}:{c}%') # a = idx_name,b=done%,c=62.25,
表示换行
,legend_opts=opts.LegendOpts(is_show=False)
)
chart.render('idx_name_Completion%.html')
chart.render_notebook()
(5)词云图
功能:展示关键词频数的图表
示例代码:
from pyecharts.charts import WordCloud
#data=pd.read_excel('')
name=['流浪地球2','满江红','熊出没','无名','英雄'] #data['movies']
value=[1000,1200,500,300,280] #data['ticket']
data1=[z for z in zip(name,value)]
chart=WordCloud()
chart.add('ticket',data_pair=data1,word_size_range=[6,20],shape='diamond') # shape可改变词云图的外形轮廓
chart.set_global_opts(
title_opts=opts.TitleOpts(title='ticket analysis',title_textstyle_opts=opts.TextStyleOpts(font_size=30))
,tooltip_opts=opts.TooltipOpts(is_show=True)
)
chart.render('ticket-wordcount.html')
三、嵌入到ppt
