一、pyecharts 地图绘制
1、pyecharts 地图绘制步骤
首先 , 导入 pyecharts 中的 Map 类 , 这是 地图绘制 的核心类 , 该类定义在 pyecharts.charts 中 ;
# 导入 pyecharts 模块中的 地图 Map 对象
from pyecharts.charts import Map
然后 , 创建 Map 类实例对象 , 该对象对应着一张地图 ;
# 创建地图对象
map = Map()
再后 , 准备要绘制的数据 , 数据类型是列表类型 , 列表元素是 元组 容器 , 元组中第一个元素是对应的 地图中的 地名 ;
# 要绘制的数据
data = [
("北京", 222),
("河北", 40),
("台湾", 8)
]
再后 , 调用 Map#add 函数 , 将数据设置到 Map 实例对象中 , 第一个参数是地图名称 , 第二个参数是 地图数据 , 第三个参数是地图类型 , 默认为 china ;
# 地图名称 : "中国地图"
# 地图数据 : data
# 地图类型 : "china"
map.add("中国地图", data, "china")
最后 , 调用 Map#render() 函数 , 生成地图 ;
# 生成图表
map.render()
运行程序 , 会生成一个 render.html 网页文件 ;
2、代码示例 - pyecharts 地图绘制

# 导入 pyecharts 模块中的 地图 Map 对象
from pyecharts.charts import Map
# 创建地图对象
map = Map()
# 要绘制的数据
data = [

("河北", 40),
("台湾", 8)
]
# 地图名称 : "中国地图"

map.add("中国地图", data, "china")

3、代码示例 - 为地图进行全局配置
首先 , 导入 视觉映射配置类 VisualMapOpts , 该类定义在 pyecharts.options 中 ;
# 导入 视觉映射配置 对象
from pyecharts.options import VisualMapOpts
然后 , 调用 Map#set_global_opts() 函数 , 设置全局配置 ; 使用关键字参数 , 指定 visualmap_opts 参数为 VisualMapOpts 类型实例对象 ;
- 在 VisualMapOpts 构造函数中 , 指定 is_piecewise 为 True , 允许手动校准范围 ;
- 在 VisualMapOpts 构造函数中 , 指定 pieces 参数 , 设置一个 列表 , 列表元素为字典 , 配置 范围参数 ;
# 设置全局配置
map.set_global_opts(
visualmap_opts=VisualMapOpts(
is_show=True,
is_piecewise=True, # 允许手动校准范围
pieces=[
{"min": 1, "max": 9, "label": "1-9", "color": '#FF0000'},
{"min": 10, "max": 99, "label": "10-99", "color": '#00FF00'},
{"min": 100, "max": 999, "label": "100-999", "color": '#0000FF'}
]
)
)
