负值如何能显示在y轴右侧？echarts 柱状配置项内容和展示

现在项目需求是负值和正值数据都要显示在Y轴的右侧，而且负值要标注为负值，不能标注为正，求大神帮忙解决，多谢！！

      var Color = ['#e4393c', '#2e8d94'];
// var data= ['12','32','-91','34','76','-20'];
var data=[{value:12,label:{formatter:'12'}},
{value:32,label:{formatter:'32'}},
{value:91,label:{formatter:'-91'}},
{value:34,label:{formatter:'34'}},
{value:76,label:{formatter:'76'}},
{value:20,label:{formatter:'-20'}}]
var xData = function() {
        var data = [];
        for (var i = 2011; i < 2017; i++) {
            data.push(i + "年");
        }
        return data;
    }();
