<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

var data = [
  ['Year', 'Sales'],
  ['2016', 1000],
  ['2017', 1170],
  ['2018', 660],
  ['2019', 1030]
];

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

function drawChart() {
  var chartData = google.visualization.arrayToDataTable(data);

  var options = {
    title: 'Sales Data',
    height: 400 // 设置图表的高度
  };

  var chart = new google.visualization.BarChart(document.getElementById('chart_div'));
  chart.draw(chartData, options);
}

<div id="chart_div"></div>

#chart_div {
  height: 400px;
}
