echart地圖城市經(jīng)緯度

使用geo時，導(dǎo)入china.js，填數(shù)劇時，前兩列映射到經(jīng)緯度，第三列映射到值,嵌套數(shù)組

echart地圖各區(qū)域顏色自定義

如何填入地區(qū)顏色？

geo.regions:areaColor(),//偽代碼

//地圖樣式 geo:{map:'china',//設(shè)置滾輪縮放地圖roam:true,//區(qū)域名字設(shè)置label:{position:'top',normal:{show:true,textStyle:{fontSize:14,color:'#eee'}},emphasis:{textStyle:{fontSize:14,color:'#fff'}}},//省份填充顏色regions:areaColor(),itemStyle:{borderColor:'rgba(255,255,255,0.5)',borderWidth:1,//設(shè)置地圖區(qū)域陰影shadowColor:'rgba(255,255,255,0.5)',//shadowColor:'rgba(0,0,0,1)',//shadowOffsetX:-2,//shadowOffsetY:2,shadowBlur:7},emphasis:{itemStyle:{color:'#ffb248'},borderWidth:0}}, //視覺映射 右上角 visualMap:[{top:10,right:10,min:100,max:8000,//映射第2列的數(shù)據(jù)dimension:2,//tip分段型type: 'piecewise',textStyle:{color: '#fff',},borderRadius:3,//tip框背景//backgroundColor:'rgba(0, 0, 0,0.5)',pieces:[{min:5000},{min:1000,max:5000},{min:500,max:1000},{min:100,max:500},{min:0,max:100}],inRange:{color:['#333','green','blue','red','#fff']}} ],

series中映射到map的data項

{ type:'effectScatter', zlevel:2, symbol:'triangle', symbolSize:12, opacity:1, //設(shè)置漣漪效果 rippleEffect:{scale:2.5 }, tooltip:{formatter:function(param){return ["城市: "+ param.data[3]+'</br>'+"訂單數(shù)量: "+ param.data[2]]} }, itemStyle:{borderType:'solid',borderColor:'#eee',//opacity:0.2,//borderWidth:1,//shadowColor:'rgba(0,0,0,0.8)',//shadowBlur:15 }, emphasis:{itemStyle:{opacity:1}}, encode: {tooltip:[3,2]}, coordinateSystem:'geo', map:'china', //dimensions:["經(jīng)度", "緯度", "訂單數(shù)量"], data:convertData(data) },
