pycharts实现地图可视化(世界地图、中国地图、省份地图)
使用之前先导入包，pycharts的1.x版本和0.5不兼容，我的环境之前是1.x版本，所以下面都是以1.x版本为例。
from pyecharts.charts import Map
from pyecharts.charts import *
from pyecharts.globals import ThemeType
from pyecharts import options as opts
#创建一个map对象
#init_opts用来初始化配置
#初始化配置项包括
'''
# 图表画布宽度，css 长度单位。
width: str = "900px",
# 图表画布高度，css 长度单位。
height: str = "500px",
# 图表 ID，图表唯一标识，用于在多图表时区分。
chart_id: Optional[str] = None,
# 渲染风格，可选 "canvas", "svg"
# # 参考 `全局变量` 章节
renderer: str = RenderType.CANVAS,
# 图表标题
page_title: str = "Awesome-pyecharts",
# 图表样式
theme: str = "white",
# 图表背景颜色
bg_color: Optional[str] = None,
# 远程 js host，如不设置默认为 https://assets.pyecharts.org/assets/"
# 参考 `全局变量` 章节
js_host: str = "",
'''
china_map = Map(init_opts=opts.InitOpts(theme=ThemeType.MACARONS ,width="1000px",height='700px',page_title="2019_nCoV-中国疫情地图"))
#全局配置项
china_map.set_global_opts(title_opts=opts.TitleOpts(title="2019_nCoV-中国疫情地图"))
#series_name
#maptype是地图的类型china就是中国地图，world就是世界地图
#湖北就是湖北地图，山东就是山东地图，is_selected=True,#控制开始时位于图标上方的小按钮是否选中
china_map.add(series_name="确诊病例", data_pair=province_total, maptype='china', is_selected=True,#控制开始时的小按钮是否选中
center=["100%","100%"],)
china_map.set_global_opts(title_opts=opts.TitleOpts(title="2019_nCoV-中国疫情地图"),
visualmap_opts=opts.VisualMapOpts(is_piecewise=True,
pieces=[
{"min": 201, "label": '>300'},
{"min": 101, "max": 200,"label":'101-200'},
# 不指定 max，表示 max 为无限大
{"min": 10, "max": 100, "label": '10-100'},
{"min": 0, "max": 9, "label": '0-9'}]))
#is_show=True用于控制地图上是否显示省份，国家，地市的名字
china_map.set_series_opts(label_opts=opts.LabelOpts(is_show=True))
page = Page()
#创建一个页面对象，使用add方法把地图加入到该页面，用于使用一个页面显示多张图表的问题。
page.add(china_map)
#生成一个html文件
page.render(path="2019_nCoV-疫情地图.html")
pyechart给使用用户提供了一套主题样式，使用户对其的使用更加方便。pyecharts.globals中ThemeType所有主题风格，修改上面代码中的theme参数即可。
CHALK = ‘chalk’ #粉笔风
DARK = ‘dark’ #暗黑风
ESSOS = ‘essos’ #厄索斯大陆
INFOGRAPHIC = ‘infographic’ #信息图
LIGHT = ‘light’ #明亮风格
MACARONS = ‘macarons’ #马卡龙
PURPLE_PASSION = ‘purple-passion’ #紫色激情
ROMA = ‘roma’ #石榴
ROMANTIC = ‘romantic’ #浪漫风
SHINE = ‘shine’ #闪耀风
VINTAGE = ‘vintage’ #复古风
WALDEN = ‘walden’ #瓦尔登湖
WESTEROS = ‘westeros’ #维斯特洛大陆
WHITE = ‘white’ #洁白风
WONDERLAND = ‘wonderland’ #仙境
