在 Google 图表中显示 X-axis 标题

Question

我想在 Android 网络视图中使用 google charts 显示柱形图的 x-axis 标题。我试图在

中将 x-axis 标题显示为 Year

var data = google.visualization.arrayToDataTable([
    ['Year', 'Sales', 'Expenses', 'Profit'],
    ['2014', 1000, 400, 200],
    ['2015', 1170, 460, 250],
    ['2016', 660, 1120, 300],
    ['2017', 1030, 540, 350]
  ]);

但它没有显示航向。完整代码；

<html>
  <head>
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">
      google.charts.load('current', {
  callback: function () {
    drawChart();
    window.addEventListener('resize', drawChart, false);
  },
  packages:['corechart']
});

     function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ['Year', 'Sales', 'Expenses', 'Profit'],
    ['2014', 1000, 400, 200],
    ['2015', 1170, 460, 250],
    ['2016', 660, 1120, 300],
    ['2017', 1030, 540, 350]
  ]);

  var options = {
    animation:{
      duration: 1000,
      easing: 'linear',
      startup: true
    },
    height: 600,
    theme: 'material',
    title: 'Company Performance'
  };

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

Answer 1

i think 您正在寻找的选项是 --> hAxis.title

    hAxis: {
      title: 'Year'
    },

请参阅以下工作片段...

google.charts.load('current', {
  callback: function () {
    drawChart();
    window.addEventListener('resize', drawChart, false);
  },
  packages:['corechart']
});

function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ['Year', 'Sales', 'Expenses', 'Profit'],
    ['2014', 1000, 400, 200],
    ['2015', 1170, 460, 250],
    ['2016', 660, 1120, 300],
    ['2017', 1030, 540, 350]
  ]);

  var options = {
    animation:{
      duration: 1000,
      easing: 'linear',
      startup: true
    },
    height: 600,
    hAxis: {
      title: data.getColumnLabel(0)
    },
    theme: 'material',
    title: 'Company Performance'
  };

  var chart = new google.visualization.ColumnChart(document.getElementById('columnchart_material'));
  chart.draw(data, options);
}

<script src="https://www.gstatic.com/charts/loader.js"></script>
<div id="columnchart_material" style="width: 900px; height: 500px;"></div>
