ECharts之force力导引布局图——数据源说明及后端API约定
ECharts之force力导向布局图——数据源说明及后端API约定
Echarts ?
关于 Echarts 请移步这里
force 力导向图
实现方式,如:
<code>function require_EC () { require( [ 'echarts', //载入force模块 'echarts/chart/kforce' ], function (ec) { //确定需要绘制的DOM setChats(ec); } )}function setChats (ec) { var myChart = ec.init(document.getElementById('main')); myChart.setOption(option);}</code>
数据源说明
主要三个数据源: categories (数据分类)、 nodes (图表中的节点名称)、 links (图表中节点之间的链接线),具体如下图:
API开发
力导向图数据 API文档 (个人意见仅供参考)
实现功能 | 1、categories、nodes、links、数组按需加载,减轻服务器压力; 2、对展示孤岛链接的优化 3、cache data 应用 |
接口传递的主要参数以及主要值 | name、force、categories、nodes、links、cache、refresh |
返回码 | 见 返回码附件图 |
参数说明:
请求示例:(详情看图片)
示例 链接 | 返回值 | 含义 |
force-api.php?name=demo1&force=nodes | 图片详情 | 获取了 名称为 ”demo1“的力导向图表的 nodes(节点) 数据 |
force-api.php?name=demo1&force=categories | 图片详情 | 获取了 名称为 ”demo1“的力导向图表的 categories(分类) 数据,【以此类推 links 不做举例】 |
force-api.php?name=demo1_isolated_all&force=links | 图片详情 | 【如何获取 孤岛链接?】将 孤岛链接组成的图表 当成一张新的图表 即可:如图, 获取了 demo1的所有孤岛链接(demo1_isolated_all)的 links 数组 |
force-api.php?name=demo1_isolated_all&force=nodes&cache=refresh | 图片详情 | 获取了 demo1的所有孤岛链接(demo1_isolated_all)的 node 数组 并做了 强制刷新 |
注:第一次请求服务器,如果请求正确返回码将是
<code>code: "2200",message: "nodes success",</code>
第二次请求服务器 将会返回
<code>code: "3304",message: "cache:2015-01-19 15:14:43",</code>
除非加上参数 cache=refresh
缓存时间3天
