問題描述

如上圖所示：：只顯示出來了點，沒有顯示下面的飛機和弧線以下是我的代碼。。自己沒找到問題，，請各路大神幫忙看看var myChart = echarts.init(document.getElementById(’main’));

問題解答

可以嘗試在在 effect 配置中添加速度參數，形如

effect.constantSpeed = 200

另外可嘗試將 coordinateSystem 參數設置為 geo。

（個人并不熟悉這個 case，只不過湊巧使用 ECharts 實現過同樣效果，參考這里http://oms.openspeech.cn/annu...）

一個示例的配置：

option = { backgroundColor: ’transparent’, title: {text: ’’,left: ’center’,textStyle: { color: ’#fff’} }, legend: {show: false,orient: ’vertical’,top: ’bottom’,left: ’right’,data: [’地點’, ’線路’],textStyle: { color: ’#fff’} }, geo: {map: ’china’,label: { emphasis: { show: false }},roam: true,itemStyle: { normal: { areaColor: ’#1f2c43’, borderColor: ’#29416b’, // TODO borderWidth: 1 * factor }, emphasis: { areaColor: ’#2b5272’ }} }, series: [{name: ’地點’,type: ’effectScatter’,coordinateSystem: ’geo’,zlevel: 2,rippleEffect: { brushType: ’stroke’},label: { emphasis: { show: true, position: ’right’, formatter: ’{b}’ }},symbolSize: 2 * factor,showEffectOn: ’render’,itemStyle: { normal: { color: ’#46bee9’ }},data: allData.citys }, {name: ’線路’,type: ’lines’,coordinateSystem: ’geo’,zlevel: 2,large: true,effect: { show: true, constantSpeed: 200, symbol: ’pin’, symbolSize: 3 * factor, trailLength: 0},lineStyle: { normal: { color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{ offset: 0, color: ’#49bcf8’ }, { offset: 1, color: ’#ff5686’ }], false), width: 1 * factor, opacity: 0.3, curveness: 0.1 }},data: allData.moveLines }]}// 格式示例allData.citys = [{'name':'清遠市','value':[112.9175,24.3292],'symbolSize':2,'itemStyle':{'normal':{'color':'#49bcf8'}}},{'name':'韶關市','value':[113.7964,24.7028],'symbolSize':2,'itemStyle':{'normal':{'color':'#49bcf8'}}}]allData.moveLines = [{'fromName':'清遠市','toName':'合肥市','coords':[[112.9175,24.3292],[117.29,32.0581]]},{'fromName':'清遠市','toName':'北京市','coords':[[112.9175,24.3292],[116.418,39.9367]]}],
