使用echarts技术做的可视图,此外其项目包含 的技术有html、css、js、jquerry、ajax、websocket、koa等。
模拟航班飞行路线
这个动态模拟飞行路线展示的是从郑州去往其他城市的动态跃迁图。
今天分享的是“反转大地球”上面的模拟从郑州去往其他地区的动态路线,是不是看着很nice!!!
数据预处理
坐标依附于一个自定义的Echarts图层对象,也就是我们那个河南图层,
引入这个文件:
<script src="js/echarts-map-henan.js"></script>
1.地图经纬度坐标存储
首先在ECharts地图的坐标需要我们存储在一个geoCoord属性里,它是一个JS的字典对象,由键/值对组成,键表示点的名称,值则表达它的坐标,由经纬度组成,它是一个数组。
var geoCoordMap = {
// 由键/值对组成:位置名称/经纬度坐标
上海: [121.4648, 31.2891],
东莞: [113.8953, 22.901],

2.路线规划
这里规划的是毕业生从郑州去往去其他城市工作的路线(虚拟数据)
数组【起点—终点,人数】
//路线起点-终点,人数
var XAData = [
[{ name: "郑州" }, { name: "郑州", value: 79 }],
[{ name: "郑州" }, { name: "洛阳", value: 6 }],
[{ name: "郑州" }, { name: "周口", value: 14 }],
[{ name: "郑州" }, { name: "安阳", value: 10 }],
[{ name: "郑州" }, { name: "驻马店", value: 3 }],
[{ name: "郑州" }, { name: "新乡", value: 11 }],
[{ name: "郑州" }, { name: "鹤壁", value: 15 }],
[{ name: "郑州" }, { name: "开封", value: 3 }],
[{ name: "郑州" }, { name: "平顶山", value: 12 }],
[{ name: "郑州" }, { name: "商丘", value: 2 }],
[{ name: "郑州" }, { name: "信阳", value: 6 }],
[{ name: "郑州" }, { name: "许昌", value: 21 }],
[{ name: "郑州" }, { name: "焦作", value: 11 }],
[{ name: "郑州" }, { name: "北京", value: 2 }],
[{ name: "郑州" }, { name: "杭州", value: 23 }],
[{ name: "郑州" }, { name: "厦门", value: 1 }],
[{ name: "郑州" }, { name: "苏州", value: 12 }],
[{ name: "郑州" }, { name: "武汉", value: 8 }],
[{ name: "郑州" }, { name: "重庆", value: 14 }],
[{ name: "郑州" }, { name: "上海", value: 22 }],
[{ name: "郑州" }, { name: "深圳", value: 18 }],
[{ name: "郑州" }, { name: "惠州", value: 4 }]
];
3.定义converData数组
注意:这里是将路线规划中的地点名称转化为经纬度存储在数组里【经纬度在地图经纬度数组里键值对寻找,通过键找到值】
// push进去线路开始-结束地点-经纬度
var convertData = function (data) {
var res = [];
for (var i = 0; i < data.length; i++) {
var dataItem = data[i];
var fromCoord = geoCoordMap[dataItem[0].name];// 出发点的经纬度获取
var toCoord = geoCoordMap[dataItem[1].name];// 目标点的经纬度获取
if (fromCoord && toCoord) { //当经纬度都有时,将键值对push进res数组中
res.push({
fromName: dataItem[0].name,//出发地点名
toName: dataItem[1].name,//目标地点名
coords: [fromCoord, toCoord],//将出发点经纬度,目标点经纬度存放在coords数组中
value: dataItem[1].value//存value值
});
//res数组格式[[{fromName: "郑州"}, {toName: "郑州"}, {coords: [[113.665412, 34.757975],[113.665412, 34.757975]]}, {value: 79}],[...],...]
}
}
return res;
};
特效设置
上面的路线具体是由三层分布:
-
红线动态特效
-
箭头移动特效
-
坐标点特效(涟漪效果)
看代码图:
整体效果:
对于这三层我们需要使用zlevel函数配置分层,下方代码有注释。
上js代码,不懂配置函数看后面标注!
//箭头样式
var planePath =
"path://M482.73408 403.02592a40.96 40.96 0 0 1 59.71968-1.90464l144.81408 144.7936a40.96 40.96 0 1 1-57.91744 57.9584l-115.79392-115.8144-115.95776 115.95776a40.96 40.96 0 0 1-57.91744-57.93792l143.0528-143.0528z";
//var planePath = 'arrow';
var color = ["#a6c84c", "#ffa022", "#46bee9"]; //航线的颜色
var series = [];
[
["郑州", XAData]
].forEach(function (item, i) {
console.log(item[0])
series.push(
{//红线动态特效
name: item[0] + " Top1",//此时item[0]存储的是郑州,即此时name为“郑州Top1”
type: "lines",
