我想要谷歌折线图而不是年份将时间刻度(24小时)放在轴上,那么我该怎么做呢 这是Google示例折线图

<html>
  <head>
    <script type="text/javascript" src="https://www.google.com/jsapi"></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Year', 'Sales', 'Expenses'],
          ['2004',  1000,      400],
          ['2005',  1170,      460],
          ['2006',  660,       1120],
          ['2007',  1030,      540]
        ]);

        var options = {
          title: 'Company Performance'
        };

        var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
  </head>
  <body>
    <div id="chart_div" style="width: 900px; height: 500px;"></div>
  </body>
</html>

您可以使用&#34; timeofday&#34; 24小时图表的数据类型。 &#34; timeofday&#34;数据类型采用4个值的数组:[hours, minutes, seconds, milliseconds],因此下午6:31:18将输入为[18, 31, 18, 0]

var data = google.visualization.arrayToDataTable([
    ['Time of day', 'Sales', 'Expenses'],
    [[3, 30, 15, 0], 1000, 400],
    [[7, 21, 56, 0], 1170, 460],
    [[12, 49, 17, 0], 660, 1120],
    [[19, 41, 47, 0], 1030, 540]
]);
