ChartJS不使用Moment.js显示时间数据 [英] ChartJS not displaying time data using Moment.js

问题描述

我正在尝试按小时绘制给定日期的一系列数据点.数据集中并没有包含每个小时，但是我仍然想显示从0:00-23:00的时间，并绘制可用的数据点.

I am trying to map out a series of data points on a given day by the hour. Not every hour is included in the data set, however I still want to show the time from 0:00 - 23:00 and plot the data points that is available.

我的错误是

此方法未实现:找不到适配器或提供了不完整的集成.

This method is not implemented: either no adapter can be found or an incomplete integration was provided.

但是，请查看文档和此<一个href ="https://code.tutsplus.com/tutorials/getting-started-with-chartjs-scales--cms-28477" rel ="nofollow noreferrer">教程，我仍然会收到错误消息.

However, Looking at the documentation and this tutorial, I still get the error.

在我的 hourlyData 集中，x是小时，y是金额.

In my hourlyData set, x is the hour and y is the amount.

有人可以看到我在做什么错吗?

Can anyone see what I am doing wrong?

$(document).ready(function() {
  var ctx = document.getElementById('chart_hourlycalls').getContext('2d');
  var hourlyData = [{
    "x": "1",
    "y": "1"
  }, {
    "x": "3",
    "y": "2"
  }, {
    "x": "5",
    "y": "1"
  }, {
    "x": "6",
    "y": "13"
  }, {
    "x": "7",
    "y": "13"
  }, {
    "x": "8",
    "y": "5"
  }, {
    "x": "9",
    "y": "9"
  }, {
    "x": "10",
    "y": "14"
  }, {
    "x": "11",
    "y": "24"
  }, {
    "x": "12",
    "y": "5"
  }];

  var labels = hourlyData.map(e => moment(e.x, 'HH'));
  var data = hourlyData.map(e => e.y);

  var options = {
    scales: {
      yAxes: [{
        display: true,
        scaleLabel: {
          display: true,
          labelString: 'Calls'
        },
        ticks: {
          beginAtZero: true
        }
      }],
      xAxes: [{
        type: 'time',
        time: {
          unit: 'hour',
          displayFormats: {
            hour: 'HH a'
          }
        },
        display: true,
        scaleLabel: {
          display: true,
          labelString: 'Hour'
        }
      }]
    },
    tooltips: {
      enabled: true
    },
  };

  new Chart(ctx, {
    type: 'line',
    data: {
      labels: labels,
      data: data
    },
    options: options
  });
});

推荐答案

您可以尝试将moment.js脚本放在chart.js上方.但是，这是一个使用moment.js的示例，可能会为您提供帮助.

You could try to put the moment.js script above the chart.js. However here is an example of using moment.js that may help you.
