今天试用了一下ol3,效果很是不错!
ol3中有个ol.Overlay,使用这个类我们可以在地图中添加各种html要素。
下面我们在地图中添加一个饼图
html中添加一个div容器:
<div style="display: none;">
<div id='canvasDiv' ></div>
<div id="popup" title="Welcome to ol3"></div>
</div>
canvasDiv绑定到地图中:
var pie = new ol.Overlay({ position: pos, positioning: ol.OverlayPositioning.CENTER_CENTER, element: document.getElementById('canvasDiv') }); map.addOverlay(pie);
定义饼图,填充canvasDiv:
$(function () { $('#canvasDiv').highcharts({ chart: { backgroundColor: 'rgba(255, 255, 255, 0)', plotBorderColor: null, plotBackgroundColor: null, plotBackgroundImage: null, plotBorderWidth: null, plotShadow: false, 200, height: 200, }, tooltip: { pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>' }, plotOptions: { pie: { allowPointSelect: true, cursor: 'pointer' } }, title: { text: '' }, dataLabels: { enabled: false, color: '#000000', //distance: -20, connectorColor: '#000000', formatter: function() { return '<b>'+ this.point.name +'</b>: '+ this.percentage +' %'; } }, series: [{ type: 'pie', name: 'Browser share', data: [ ['Firefox', 45.0], ['IE', 26.8], { name: 'Chrome', y: 12.8, sliced: true, selected: true }, ['Safari', 8.5], ['Opera', 6.2], ['Others', 0.7] ] }] }); });
效果如下:
