摘要：
接着《Echarts引入中国地图》续写，我们的项目需求是要求地图的背景颜色要各省份不同。看了文档同时也看了相关官网例子，写出来总结下吧，以便以后需要。
实现：
1、在series中添加data[ ]数据
data: [
{ name: '北京', selected: false, value: 1 },
{ name: '天津', selected: false, value: 2 },
{ name: '上海', selected: false, value: 3 },
{ name: '重庆', selected: false, value: 4 },
{ name: '河北', selected: false, value: 5 },
{ name: '河南', selected: false, value: 6 },
{ name: '云南', selected: false, value: 7 },
{ name: '辽宁', selected: false, value: 8 },
{ name: '黑龙江', selected: false, value: 9 },
{ name: '湖南', selected: false, value: 10 },
{ name: '安徽', selected: false, value: 11 },
{ name: '山东', selected: false, value: 12 },
{ name: '新疆', selected: false, value: 13 },
{ name: '江苏', selected: false, value: 14 },
{ name: '浙江', selected: false, value: 15 },
{ name: '江西', selected: false, value: 16 },
{ name: '湖北', selected: false, value: 17 },
{ name: '广西', selected: false, value: 18 },
{ name: '甘肃', selected: false, value: 19 },
{ name: '山西', selected: false, value: 20 },
{ name: '内蒙古', selected: false, value: 21 },
{ name: '陕西', selected: false, value: 22 },
{ name: '吉林', selected: false, value: 23 },
{ name: '福建', selected: false, value: 24 },
{ name: '贵州', selected: false, value: 25 },
{ name: '广东', selected: false, value: 26 },
{ name: '青海', selected: false, value: 27 },
{ name: '西藏', selected: false, value: 28 },
{ name: '四川', selected: false, value: 29 },
{ name: '宁夏', selected: false, value: 30 },
{ name: '海南', selected: false, value: 31 },
{ name: '台湾', selected: false, value: 32 },
{ name: '香港', selected: false, value: 33 },
{ name: '澳门', selected: false, value: 34 }
] //各省地图颜色数据依赖value
2、在mapBoxOption中添加dataRange
dataRange: {
x: '-1000 px', //图例横轴位置
y: '-1000 px', //图例纵轴位置
splitList: [
{ start: 1, end: 1, label: '北京', color: '#cfc5de' },
{ start: 2, end: 2, label: '天津', color: '#f1ebd1' },
{ start: 3, end: 3, label: '上海', color: '#feffdb' },
{ start: 4, end: 4, label: '重庆', color: '#e0cee4' },
{ start: 5, end: 5, label: '河北', color: '#fde8cd' },
{ start: 6, end: 6, label: '河南', color: '#e4f1d7' },
{ start: 7, end: 7, label: '云南', color: '#fffed7' },
{ start: 8, end: 8, label: '辽宁', color: '#e4f1d7' },
{ start: 9, end: 9, label: '黑龙江', color: '#e4f1d7' },
{ start: 10, end: 10, label: '湖南', color: '#fffed7' },
{ start: 11, end: 11, label: '安徽', color: '#fffed8' },
{ start: 12, end: 12, label: '山东', color: '#dccee7' },
{ start: 13, end: 13, label: '新疆', color: '#fffed7' },
{ start: 14, end: 14, label: '江苏', color: '#fce8cd' },
{ start: 15, end: 15, label: '浙江', color: '#ddceeb' },
{ start: 16, end: 16, label: '江西', color: '#e4f1d3' },
{ start: 17, end: 17, label: '湖北', color: '#fde8cd' },
{ start: 18, end: 18, label: '广西', color: '#fde8cd' },
{ start: 19, end: 19, label: '甘肃', color: '#fde8cd' },
{ start: 20, end: 20, label: '山西', color: '#fffdd6' },
{ start: 21, end: 21, label: '内蒙古', color: '#ddcfe6' },
{ start: 22, end: 22, label: '陕西', color: '#fad8e9' },
{ start: 23, end: 23, label: '吉林', color: '#fce8cd' },
{ start: 24, end: 24, label: '福建', color: '#fad8e8' },
{ start: 25, end: 25, label: '贵州', color: '#fad8e8' },
{ start: 26, end: 26, label: '广东', color: '#ddcfe8' },
{ start: 27, end: 27, label: '青海', color: '#fad8e9' },
{ start: 28, end: 28, label: '西藏', color: '#ddcfe6' },
{ start: 29, end: 29, label: '四川', color: '#e4f1d5' },
{ start: 30, end: 30, label: '宁夏', color: '#fefcd5' },
{ start: 31, end: 31, label: '海南', color: '#fad8e9' },
{ start: 32, end: 32, label: '台湾', color: '#fce8cd' },
{ start: 33, end: 33, label: '香港', color: '#dc9bbb' },
{ start: 34, end: 34, label: '澳门', color: '#e0f7cc' },
]
}, //各省地图颜色；start：值域开始值；end：值域结束值；label：图例名称；color：自定义颜色值；3、完整的代码如下

4、运行后的效果如下
