安装与查看pyecharts

安装pyecharts

pip install pyecharts==2.0.3
# Successfully installed prettytable-3.7.0 pyecharts-2.0.3 simplejson-3.19.1

查看版本

import pyecharts
print(pyecharts.__version__) 
# 2.0.3

地图实现-BMap

pyecharts的地图实现包括:

Geo：地理坐标系
Map：地图
BMap：百度地图

本部分完成BMap坐标系实现。

案例演示

from pyecharts import options as opts
from pyecharts.charts import BMap
from pyecharts.faker import Fakerc = (BMap().add_schema(baidu_ak="FAKE_AK", center=[120.13066322374, 30.240018034923]).add("bmap",[list(z) for z in zip(Faker.provinces, Faker.values())],label_opts=opts.LabelOpts(formatter="{b}"),).set_global_opts(title_opts=opts.TitleOpts(title="BMap-基本示例")).render("bmap_base.html")
)
