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 += '<br/>' + params[i].seriesName + ' : ' + Math.abs(params[i].value) ;                                            }                                   setTimeout(function () {                                       // 仅为了模拟异步回调                                       callback(ticket, res);                                   }, 500)                                   return 'loading...';                               }            },            legend: {                data:[ '男', '女']            },            grid: {                left: '3%',                right: '4%',                bottom: '3%',                containLabel: true            },            xAxis : [                {                    axisLabel : { formatter: function (value){return Math.abs(value);//显示的数值都取绝对值                }         },                    type : 'value'                }            ],            yAxis : [                {                    type : 'category',                    axisTick : {show: false},                   // data : ['0~5岁','5~10岁','10-30岁','30-50岁','50-70岁','70-100','100以上']                    data : ageArea                }            ],            series : [                {                    name:'男',                    type:'bar',                    stack: '总量',                    label: {                        normal: {                            show: true,                            position: 'right',                        }                    },                   // data:[320, 302, 341, 374, 390, 450, 420]                    data:FbarData                },                {                    name:'女',                    type:'bar',                    stack: '总量',                    label: {                        normal: {                            show: true,                            position: 'left',                           formatter:function(v){return Math.abs(v.data)}                        }                    },                   // data:[-120, -132, -101, -134, -190, -230, -210]                    data:MbarData                }            ]        };    rkkchart.setOption(option);}
