轴的数字格式 - Google Gauge

我正在尝试更改Google测量仪上轴的数字格式。默认情况下,轴值是一个整数(例如0,120),但我想显示一个£符号和格式作为货币(例如£0,£120)。我已经能够使用NumberFormat更改仪表底部显示的值的格式,但不能应用于仪表的其余部分。

基本仪表的代码如下:

<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> 
<script type="text/javascript">
  google.charts.load('current', {'packages':['gauge']});
  google.charts.setOnLoadCallback(drawChart);

  function drawChart() {

        var data1 = google.visualization.arrayToDataTable([
          ['Label', 'Value'],
          ['Spend', 80],
        ]);
        var options1 = {
          width: 500, height: 300
        };

        // change number format to £
        var formatter = new google.visualization.NumberFormat(
        {pattern: '£###,###'});
        formatter.format(data1, 1);

        var chart = new google.visualization.Gauge(document.getElementById('chart_div1'));
        chart.draw(data1, options1);

  }
</script>
</head>

<body>
 <div id="chart_div1"></div>
</body>
</html>

如何在仪表外部的数字上添加£符号?谢谢。

您可以为majorTicks提供一系列字符串,以指定您自己的...

google.charts.load('current', {'packages':['gauge']});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
    var data1 = google.visualization.arrayToDataTable([
      ['Label', 'Value'],
      ['Spend', 80],
    ]);
    var options1 = {
      width: 500, height: 300,
      majorTicks: [
        '£0', '', '', '', '£100'
      ]
    };

    // change number format to £
    var formatter = new google.visualization.NumberFormat({
      pattern: '£###,###'
    });
    formatter.format(data1, 1);

    var chart = new google.visualization.Gauge(document.getElementById('chart_div1'));
    chart.draw(data1, options1);
}
