右对齐条JQPlot

Question

我使用jqPlot生成了以下图表，但由于某种原因，条形图始于xAxis的中间。

我需要将它们移到右侧，我查看了文档并且无法解决问题。有什么建议吗？

$(document).ready(function(){   
    var ok_before = [4, 3, 1, 0];
    var ok_bars = [3, 4, 5, 4];
    var ok_after = [1, 1, 2, 4];

    var err_before = [5, 0, 2, 0];
    var err_bars = [1, 0, 2, 0];
    var err_after = [2, 8, 4, 8];

    var dateticks = [['2014-01-01' ], ['2014-01-02' ], ['2014-01-03' ], ['2014-01-04' ], ['2014-01-05'], ['2014-01-06'], ['2014-01-07'], ['2014-01-08']];
    var xaxis2ticks = ['We', 'Th', 'Fr', 'Sa', 'Su', 'Mo', 'Tu', 'We']
    var yvals = ['WO1028', 'WO1026', 'WO1025', 'WO1024'];

    plot1 = $.jqplot('chart3', [ok_before, ok_bars, ok_after], {
        animate: true, animateReplot: true,
        series:{
            renderer:$.jqplot.BarRenderer, 
            xaxis:'x2axis'
        }, 
        gridPadding: {bottom: 55, top: 10},
        stackSeries: true,
        seriesColors: ['rgba(100, 150, 100, 0)', "#009900"], 
        seriesDefaults:{
            renderer:$.jqplot.BarRenderer,
            rendererOptions: {
                barMargin: 30,
                barDirection: 'horizontal',          
                shadow: false, 
                varyBarColor: true,

        },
        axes: {

                renderer: $.jqplot.CategoryAxisRenderer, 
                //padMin: 0, 
                ticks: dateticks, 
                tickInterval: '1 day', 
            }, 
            x2axis: {
                renderer: $.jqplot.CategoryAxisRenderer, 
                //padMin: 0, 
                ticks: xaxis2ticks, 
            }, 
            yaxis: {
                ticks: yvals,
