给3D地图增加3D柱状图应用的性能原理是在地图上加上圆柱对象，能够用色彩和高度别离代表分类和值大小，依据须要将柱状图搁置到指定地位即可。3D地图与3D柱状图联结应用，成果大略是这样：
注：依据你我的项目需要的不同，须要的可能是整个中国的地图数据，也可能是某个省的，市的，县的，区的等，这时怎么办？
- 去网上搜有很多，然而可能数据不全，或者会员能力下载。
2、CityBuilder 提供了多种天文图形素材，一键生成初始模板，几乎是神器！
长处在于一般开发人员也能顺手搭建3D地图，能够疾速利用于三维城市我的项目。反对多种修建、路网、河流等图层的动效渲染，能够在此基础上构建出折线图、柱状图、散点图、K线图、饼图等等，同时反对多图表混合展示等。让大屏变平面就是如此简略！
配合上图表还能够做出更优良，更酷炫的成果！
看一下3D地图与3D柱状图联结应用的实现代码吧！
