echarts地图线性动画
最近搞可视化,个了demo,⾃⼰研究的下(忘记原⽂地址了),改了改了,当做记录以便以后复习:

// 基于准备好的dom,初始化echarts实例
var myChart = echarts.ElementById('main'));
// 指定图表的配置项和数据
var chinaGeoCoordMap = {

'⿊龙江': [127.9688, 45.368],

// 然后再定义个chinaDatas数组,来存放⼀些数据,如:
var chinaDatas = [
[{
name: '深圳市',
value: 0
},{
name: '⿊龙江',
value: 0
}], [{
name: '内蒙古',
value: 0
}], [{
name: '吉林',
value: 0
}], [{
name: '辽宁',
value: 0
}], [{
name: '河北',
value: 0
}], [{
name: '天津',
value: 0
}], [{
name: '⼭西',
value: 0
}]
];
// 可以根据你实际项⽬需求来添加你的数据。
// 定义中⼼点和起始点,代码如下:
var convertData = function(data) {
var res = [];
for(var i = 0; i < data.length; i++) {
var dataItem = data[i];
var fromCoord = chinaGeoCoordMap[dataItem[0].name];
var toCoord = [114.06229447753907,22.54758268442238];//中⼼点地理坐标 if(fromCoord && toCoord) {
res.push([{
coord: toCoord,
},
{
js文字动画特效coord: fromCoord,
value: dataItem[0].value
}]);
}
}
console.log(res)
return res;
};
var series = [];
[['⼭西', chinaDatas]].forEach(function(item, i) {
console.log(item)
