echats柱状图分组显示不同的标签

平常我们应用多的场景是，按照一定分组显示，如下图。

但是现在如果每年的柱子的名字不一样，可以参考下面的代码，在label的formatter中进行处理。

<div style="text-align:center; font-size: 24px; padding: 20px;">
	近三年金额排在前5位的单位
</div>

<div style="text-align:center;width:800px;height:500px;margin-left:auto;margin-right:auto;" id="sta_container">

</div>




<script type="text/javascript">


var resultRes = {};
resultRes._DATA_ = {};
resultRes._DATA_.unitMoney1 = '[{"value":91, "name":"name1"},{"value":89, "name":"name2"},{"value":85, "name":"name3"}]';
resultRes._DATA_.unitMoney2 = '[{"value":153, "name":"XXXX1"},{"value":120, "name":"XXXX2"},{"value":76, "name":"XXXX3"}]';
resultRes._DATA_.unitMoney3 = '[{"value":76, "name":"随心所欲"},{"value":97, "name":"任性"},{"value":132, "name":"YYYYY3"}]';
resultRes._DATA_.unitMoney4 = '[{"value":167, "name":"ZZZZZ1"},{"value":123, "name":"ZZZZZ2"},{"value":176, "name":"就是这么拽"}]';
resultRes._DATA_.unitMoney5 = '[{"value":189, "name":"OOOOO1"},{"value":112, "name":"OOOOO2"},{"value":83, "name":"OOOOO3"}]';

var dom = document.getElementById("sta_container");
var myChart = echarts.init(dom);

var labelOption = {
   normal: {

   series: [
