漏刻有时数据可视化Echarts组件开发(41)svg格式地图应用

1.定义SVG文件

var svg = ``;

2.注册地图函数

Echarts.registerMap是Echarts图表库中用于注册地图的函数。它可以将第三方地图或自定义地图数据与Echarts进行集成，使用Echarts的API进行绘制。使用方法如下：
echarts.registerMap(mapName, geoJson) 参数mapName是地图的名称,geoJson是地图的数据。注册后可以使用这个地图名称在Echarts中使用这个地图。如有需要，建议咨询Echarts官方网站或者查询专业书籍。

echarts.registerMap("organ_diagram", { svg: svg });

3.核心代码

const datas = {from: [300, 400],to: [{name: "永嘉",value: 2,coord: [600, 100],},{name: "乐清",value: 5,coord: [700, 150],},{name: "瑞安",value: 8,coord: [400, 300],},{name: "瓯海",value: 10,coord: [550, 300],},],
};option = {backgroundColor: "#040b1c",title: {text: "Visit Route",left: "center",bottom: 10,},tooltip: {trigger: "item",backgroundColor: "rgba(166, 200, 76, 0.82)",borderColor: "#FFFFCC",showDelay: 0,hideDelay: 0,enterable: true,transitionDuration: 0,extraCssText: "z-index:100",formatter: function (params, ticket, callback) {console.log(params);//根据业务自己拓展要显示的内容var res = "";var name = params.name;var value = params.value[params.seriesIndex + 1] || params.value;res = "<span style='color:#fff;'>" + name + "</span><br/>数据：" + value;return res;},},visualMap: {//图例值控制min: 0,max: 10,calculable: true,show: false,color: ["#f44336", "#fc9700", "#ffde00", "#ffde00", "#00eaff"],textStyle: {color: "#fff",},},geo: {left: 10,right: 10,map: "organ_diagram",itemStyle: {borderWidth: 0,},emphasis: {focus: "none",itemStyle: {areaColor: "#ff0000",},label: {show: false,},},regions: [{name: "map12",itemStyle: {areaColor: "red",color: "red",},},],},series: [],
};myChart.setOption(option);myChart.on("click", function (event) {console.log(event);myChart.dispatchAction({type: "highlight",geoIndex: 0,name: event.name,});
});
