Question

我正在尝试用2行创建一个JQ Plot。第一行每小时都有第1天的数据，第二行是每小时数据的第2行。当我使用这两行创建图表时，我希望在第二行的顶部显示一行来显示每小时数据比较。但我在图表上看到这两条线彼此相邻。

我有样本here

请告诉我如何调整图表选项以在另一行上方显示一行。谢谢。

这是我的代码：

我在同样的问题上挣扎。

解决方案是定义第二个x轴，我们将其命名为x2axis。

然后在你的系列配置中，指定你的一个系列将使用第二个x轴。

var plot1 = $.jqplot('chart1', [line1,line2], { 
    title: 'XYZ, Inc.', 
    series: [{ 
        label: 'primary series', 
        neighborThreshold: -1,
        xaxis: 'xaxis'
    }, {
        label: 'comparative series',
        xaxis: 'x2axis'
    }], 
    axes: { 
        xaxis: { 
            renderer:$.jqplot.DateAxisRenderer,
            tickRenderer: $.jqplot.CanvasAxisTickRenderer,
            tickOptions: {
              angle: -30
            } 
        },
        x2axis: {
            renderer:$.jqplot.DateAxisRenderer,
            tickRenderer: $.jqplot.CanvasAxisTickRenderer,
            tickOptions: {
              angle: -30
            } 
        },
        yaxis: {  
            renderer: $.jqplot.LogAxisRenderer,
            tickOptions:{ prefix: '$' } 
        } 
    }, 
    cursor:{
        show: true, 
        zoom: true
    } 
});

如果您使用dateAxisRenderer，我认为不可能，可能的解决方案是使用带有dateAxisRenderer的折线图

例如：

line1 = [[10,425.32], [11,424.84], [12,417.23], [13,390], [14,393.69], [15,392.24], [16,369.78], [17,330.16], [18,308.57], [19,346.45], [20,371.28], [21,324.7]];

line2 = [[10,325.32], [11,324.84], [12,217.23], [13,190], [14,593.69], [15,292.24], [16,369.78], [17,330.16], [18,308.57], [19,446.45], [20,241.28], [21,624.7]];

var plot3 = $.jqplot('chart1', [line1, line2 ], { 
  title: 'XYZ, Inc.', 
    series: [{ 
        label: 'XYZ, Inc.', 
        neighborThreshold: -1 
    }], 
    axes: {
        xaxis: {
            min: 1,
            max: 24,
            tickInterval: 2,
            tickOptions:{ suffix: ':00' } 
        },
         yaxis: {  
            renderer: $.jqplot.LogAxisRenderer,
            tickOptions:{ prefix: '$' } 
        } 
    },
    cursor:{
        show: true, 
        zoom: true
    } 
});

它为我工作。

示例：

var line1=[['2008-06-30 8:00AM',4], ['2008-7-14 8:00AM',6.5], ['2008-7-28 8:00AM',5.7], ['2008-8-11 8:00AM',9], ['2008-8-25 8:00AM',8.2]];
var line2=[['2008-06-30 8:00AM',6], ['2008-7-14 8:00AM',8.5], ['2008-7-28 8:00AM',8.7], ['2008-8-11 8:00AM',12], ['2008-8-25 8:00AM',8.2]];

var plot2 = $.jqplot('chart3', [line1,line2], {
    title:'Customized Date Axis', 
    axes:{
        xaxis:{
          renderer:$.jqplot.DateAxisRenderer, 
          tickOptions:{formatString:'%b %#d, %#I %p'},
          min:'June 16, 2008 8:00AM', 
          tickInterval:'2 weeks'
        }
    },
    series:[{lineWidth:4, markerOptions:{style:'square'}}]
});
