【python笔记】datafram的时间动态可视化 pyecharts地图

import pandas as pd# 假设DataFrame是这样的：  
df = pd.DataFrame({  'year': [2014, 2015, 2016, 2014, 2015, 2016, 2014, 2015, 2016],  'province': ['广东省', '广东省', '河南省', '湖南省', '北京市', '北京市', '上海市', '新疆维吾尔自治区', '上海市'],  'values': [100, 150, 75,120, 80, 200, 110, 200, 190]  
})

from pyecharts import options as opts
from pyecharts.charts import Map, Timeline
from pyecharts.globals import CurrentConfig, NotebookType# 设置jupyter lab可视的前提条件
CurrentConfig.NOTEBOOK_TYPE = NotebookType.JUPYTER_LAB# 按照年份对DataFrame进行分组，以便为每个年份创建地图  
grouped_df = df.groupby('year')  t = Timeline()  # 遍历分组后的数据，为每个年份创建地图并添加到Timeline中  
for year, year_df in grouped_df:  # 创建Map对象，并添加数据map_chart = (  Map()  .add(series_name="商家A", data_pair=year_df[['province', 'values']].to_numpy(), maptype="china")   .set_series_opts(label_opts=opts.LabelOpts(is_show=False))     # 是否显示省份名称.set_global_opts(title_opts=opts.TitleOpts(title=f"Map-{year}年某些数据"),  visualmap_opts=opts.VisualMapOpts(max_=df['values'].quantile())  # 默认值min_=0, max_=100。即是否用不同深浅的颜色填充MAP)  )  # 将地图添加到Timeline中，并设置时间点的名称  t.add(chart=map_chart, time_point="{}年".format(year))  # def timeline.add(self, chart: Base, time_point: str):t.render_notebook()
