1. ColumnarStatistics

柱状统计图 基于entity图形数据图层。包括多边形

1.1.1. new ColumnarStatistics(options)

Example

//生成柱状统计
let colSta = new BOSGeo.ColumnarStatistics({
    name: '图形', //名称
    geojsonUrl: './resource/data/422800.json', //geojson的Url。不设置则为undefined
    show: true, //显隐控制
    isZoomTo: true,//是否加载时缩放至
    staticField: 'id',
    // extrudedHeight:10,  //图形拉伸高度
    color: '#49a8f9',   //图形颜色  
    opacity: 1, //不透明度
    height: 100, //地面高度
    extrudedHeight: 10000, //拉伸高度
    riseTime: 5, //拉伸生长时间间隔
    radius: 1000, //半径
    onClick: true //是否点击查询
});
