javascript - Highstock dateTimeLabelFormats 不起作用

Question

我试图在 Xaxis 中仅显示该月的第一天，一切正常系列数组有超过或等于五个元素:

http://jsfiddle.net/2f6Ne/

data: [
        [ Date.UTC(2014, 0, 1), 10.82413772161932 ],
        [ Date.UTC(2014, 1, 1), 0.10286926951274679 ],
        [ Date.UTC(2014, 2, 1), 0.4359489916094994 ],
        [ Date.UTC(2014, 3, 1), 0.4359489916094994 ],
        [ Date.UTC(2014, 4, 1), 0.4359489916094994 ]
    ]

但是当系列少于五个元素时，dateTimeLabelFormats 选项不起作用: http://jsfiddle.net/XtFnx/

  data: [
        [ Date.UTC(2014, 0, 1), 10.82413772161932 ],
        [ Date.UTC(2014, 1, 1), 0.10286926951274679 ],
        [ Date.UTC(2014, 2, 1), 0.4359489916094994 ],
        [ Date.UTC(2014, 3, 1), 0.4359489916094994 ]
    ]

有什么想法吗？

虽然我不确定你在问什么，但我是否隐约猜到你想在 x 轴上显示每个月的第一天。如果是，你可以使用 tickPositioner。

tickPositioner: function() {

                     var ticks = [
                    Date.UTC(2014, 0, 1),
                    Date.UTC(2014, 1, 1), 
                    Date.UTC(2014, 2, 1), 
                    Date.UTC(2014, 3, 1)];
                    //dates.info defines what to show in labels
                    //apparently dateTimeLabelFormats is always ignored when specifying tickPosistioner

                     ticks.info = {
                    //unitName: "month", 
                    unitName: "day",
                    higherRanks: {} // Omitting this would break things
                };           
                return ticks;
            }
