CharJS中Y轴的时间尺度转换

Question

我使用Chart JS绘制图表。

有什么问题？ /我想要什么？
Y轴刻度值应更改为HH：MM：SS格式。但它不起作用。

这是我传递的数据对象：

Preview

secondsToHms（）功能：

    function secondsToHms(totalSec){
        var hours = parseInt( totalSec / 3600 ),
        minutes = parseInt( totalSec / 60 ) % 60,
        seconds = totalSec % 60;

        return (hours < 10 ? "0" + hours : hours) + ":" + (minutes < 10 ? "0" + minutes : minutes) + ":" + (seconds  < 10 ? "0" + seconds : seconds);
    }

遵循的步骤： https://github.com/chartjs/Chart.js/issues/2791#issuecomment-237690528 具体是下面提到的部分：

scales: {
    yAxes: [{
      ticks: {
        userCallback: function(v) { return epoch_to_hh_mm_ss(v) },
        stepSize: 30 * 60
      }
    }]
  },
  tooltips: {
    callbacks: {
      label: function(tooltipItem, data) {
        return data.datasets[tooltipItem.datasetIndex].label + ': ' + epoch_to_hh_mm_ss(tooltipItem.yLabel)
      }
    }
  }
