放上json文件：
{ "2017年3月": { "outKou": "5525.86", "inKou": "420833.61", "outLooper": null, "inLooper": null }, "2017年4月": { "outKou": "6508.79", "inKou": "252569.23", "outLooper": null, "inLooper": null }, "2017年5月": { "outKou": "4649.94", "inKou": "139571.47", "outLooper": "-28.56", "inLooper": "-44.74" }, "2017年6月": { "outKou": "3363.42", "inKou": "73648.86", "outLooper": "-27.67", "inLooper": "-47.23" }, "2017年7月": { "outKou": "2978.7", "inKou": "284503.52", "outLooper": "-11.44", "inLooper": "286.3" }, "2017年8月": { "outKou": "7093.42", "inKou": "287138.07", "outLooper": "138.14", "inLooper": "0.93" }, "2017年9月": { "outKou": "4675.65", "inKou": "275385.15", "outLooper": "-34.08", "inLooper": "-4.09" } }
数据格式就是这样的，先放上效果图再放上代码：
（js插件就不放了，找往期的可以找到，看日期找最新的图表实战就可以了）

里面的url可以自己把上面的json数据放到一个json文件里面，url进行引入同样的效果
