将水平条形图旋转到垂直图表

Question

Saw this graph on JSFiddle。我用自己的数据修改了它，但是我想要一个垂直条形图而不是水平条形图。 Here's what it looks like now。我试着摆弄X轴和Y轴，但似乎无法做到正确。任何帮助将不胜感激。

这是我的代码：

var margins = {
    top: 12,
    left: 48,
    right: 24,
    bottom: 40
},

legendPanel = {
    width: 180
},
width = 400 - margins.left - margins.right - legendPanel.width,
    height = 200 - margins.top - margins.bottom,
    dataset = [{
        data: [{
            year: '2009',
            count: 80
        }, {
            year: '2010',
            count: 79
        }, {
            year: '2011',
            count: 65
        }, 
                {
            year: '2012',
            count: 70
        },
                    {
            year: '2013',
            count: 72
        } ,
                    {
            year: '2014*',
            count: 38
        } 
              ],
        name: 'Male'
    }, {
        data: [{
            year: '2009',
            count: 15
        }, {
            year: '2010',
            count: 17
        }, {
            year: '2011',
            count: 18
        }, {
            year: '2012',
            count: 20
        }, {
            year: '2013',
            count: 17
        },

              {
            year: '2014*',
            count: 8
        }],
        name: 'Female'
    }
