问题描述

我能够创建热图,但点没有显示:

import folium
import folium.plugins as plugins
import numpy as np
import pandas as pd
import geopandas as gpd
from folium import Choropleth, Circle, Marker
from folium.plugins import HeatMap, MarkerCluster, HeatMapWithTime
ucdp_df = pd.read_csv('csv/ged201.csv') # from https://ucdp.uu.se/downloads/index.html#ged_global
ucdp = gpd.GeoDataFrame(ucdp_df, geometry=gpd.points_from_xy(ucdp_df.longitude, ucdp_df.latitude))
ucdp.crs = {'init': 'epsg:4326'}
m = folium.Map([35, 41], tiles='stamentoner', zoom_start=6)
hm = HeatMapWithTime(data=ucdp[['latitude', 'longitude']].values.tolist(),
                     index=ucdp['year'].values.tolist(), 
                     radius=10,
                     auto_play=True,
                     max_opacity=0.3)
hm.add_to(m)
m

推荐答案

您需要以正确的格式提供数据。这应该是可行的:

from collections import defaultdict, OrderedDict

data = defaultdict(list)
for r in ucdp_df.itertuples():
    data[r.year].append([r.latitude, r.longitude])
    
data = OrderedDict(sorted(data.items(), key=lambda t: t[0]))

然后使用数据:

m = folium.Map([35, 41],
               tiles='stamentoner',
               zoom_start=6)


hm = HeatMapWithTime(data=list(data.values()),
                     index=list(data.keys()), 
                     radius=10,
                     auto_play=True,
                     max_opacity=0.3)
hm.add_to(m)
m

您会得到:
