echarts 实现柱状图左右横向显示

具体实现代码如下 解决echarts 负轴，浮动负数，等的显示

function chart_rkk(){
    var rkkchart=echarts.init(document.getElementById('rkkDiv'));
    var ageArea = [ '0~10','11~30','30~60','60~100','100以上'];
    var FbarData = [3100, 2142, 1218, 581, 431]; //男
    var MbarData = [-3010, -2742, -218, -381, -521]; //女

    option = {
            tooltip : {
                trigger: 'axis',
                axisPointer : {            // 坐标轴指示器，坐标轴触发有效
                    type : 'shadow'        // 默认为直线，可选为：'line' | 'shadow'
                },
                 formatter: function (params, ticket, callback) {
                                   console.log(params)
                                   var res = params[0].name ;
                                   for (var i = 0, l = params.length; i < l; i++) {
                                       res += '
' + params[i].seriesName + ' : ' + Math.abs(params[i].value) ;     
                                       }
                                   setTimeout(function () {
                                       // 仅为了模拟异步回调
                                       callback(ticket, res);
                                   }, 500)
