Google图表：如何在面积图上添加缩放按钮

我想像AnnotationChart一样在AreaChart顶部添加缩放按钮。我搜索了相同的内容，但没有找到解决方案。谁能告诉我解决方案？我需要这样的按钮：

谢谢

您必须手动添加按钮，
单击后，使用state属性 在范围过滤器上设置可见范围

  rangeFilter.setState({
    range: {
      start: currentRange.range.start,
      end: new Date(currentRange.range.start.getTime() + visibleRange)
    }
  });

参见以下工作片段，
每个按钮代表可见范围（以毫秒为单位），
单击后在过滤器上设置范围...

  rangeFilter.setState({
    range: {
      start: currentRange.range.start,
      end: new Date(currentRange.range.start.getTime() + visibleRange)
    }
  });

google.charts.load('current', {
  packages: ['controls', 'corechart']
}).then(function () {
  var data = new google.visualization.DataTable();
  data.addColumn('date', 'Date');
  data.addColumn('number', 'Positive');
  data.addColumn('number', 'Negative');
  data.addRows([
