【问题描述】：

我是新来的，是朋友介绍的。我正在使用谷歌图表，连接到谷歌表格。我的图表工作正常。下一步是在其底部添加一个工具栏。但是，无论如何，我都无法使代码正常工作。我什至尝试将Google's example code 复制并粘贴到空白页中进行测试，但我什至无法展示他们的示例。文档中是否缺少阻止这种情况的内容？这是我的代码：

【解决方案1】：

似乎在这里工作，有几个小的调整。

通常，setOnLoadCallback 每页只能调用一次。
这很可能是问题所在。
在这里，我在load 语句中定义了callback。

// Load the Visualization API and the piechart package.
google.charts.load('current', {
  callback: drawChart,
  packages:['corechart']
});

function drawChart() {
  var query = new google.visualization.Query("https://docs.google.com/spreadsheets/d/1m3ujxzPQJh3haReNDzGGF73Mh6-u6HxyCVPK_5MK2hw/gviz/tq?sheet=Sheet2&range=A1:E5");
  query.send(handleQueryResponse);
}

function handleQueryResponse(response) {
  var data = response.getDataTable();
  var options = {
    'title':'College Readiness',
    'titleTextStyle': {fontSize: '24', color: 'teal'},
    //'width':800,
    'height':600,
    hAxis: {'title': 'Academic Year', 'textStyle': {bold: true, fontSize: '16'}},
    vAxis: {'title': 'Percent of Students Ready', 'format': 'percent','textStyle': {color: 'gray', fontSize: '9'}},
    legend: {'position': 'top'},
    series: {
        0: {pointsVisible: true, color: 'orange'},
        1: {pointsVisible: true, color: 'blue'},
        2: {pointsVisible: true, color: 'black'},
        3: {pointsVisible: true, pointShape: 'square', pointSize: '14', color: 'maroon'}
    }
  };
  var chart = new google.visualization.LineChart(document.getElementById('chart_div'));
  chart.draw(data, options);

  var components = [
    {type: 'html', datasource: 'https://docs.google.com/spreadsheets/d/1m3ujxzPQJh3haReNDzGGF73Mh6-u6HxyCVPK_5MK2hw/gviz/tq?sheet=Sheet2&range=A1:E5'},
    {type: 'csv', datasource: 'https://docs.google.com/spreadsheets/d/1m3ujxzPQJh3haReNDzGGF73Mh6-u6HxyCVPK_5MK2hw/gviz/tq?sheet=Sheet2&range=A1:E5'}
  ];

  var container = document.getElementById('toolbar_div');
  google.visualization.drawToolbar(container, components);
}

非常感谢。这正是我所需要的。
