我正在尝试通过计算每个值，使用谷歌可视化 API 从单列数据创建饼图，但我不断收到以下错误消息：

Invalid query: SELECT_WITH_AND_WITHOUT_AGG: C

信息

我的电子表格可以在这里找到： https ://docs.google.com/spreadsheets/d/1lmmpJs2Bz3EfQWExB4KXq_uJWoLlq1PMCahy6w4ipcE/edit#gid=942634171

我想要做的是创建一个饼图，计算“你来自哪个社区”列中的唯一值并绘制它们的相对比例。

列本身可以在这里看到：

电子表格列的图片

所以我想拿这一列并从中创建一个表，如下所示：

示例表

Corona                     2
Sunnyside                  3
Elmhurst                   4

等等。然后使用字符串/数字组合来填充饼图。

使用常规 SQL，您可以执行 SELECT Column、COUNT(Column) GROUP BY Column，所以我假设类似的东西适用于 GQL。

到目前为止，这些是我尝试过的一些查询：

查询：

'SELECT COUNT(C) GROUP BY C'
'SELECT C, COUNT(C) GROUP BY C'
'SELECT C, COUNT(C) PIVOT C

但这些都没有奏效。

我还在控制台中收到此错误消息：

错误信息：

控制台消息

这是我正在使用的与我的问题有关的脚本：

脚本

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

  // Set a callback to run when the Google Visualization API is loaded.
  google.charts.setOnLoadCallback(drawChart);
    function drawChart() {
        var neighborhoodChart = new google.visualization.ChartWrapper({
        'chartType'     : 'PieChart',
        'containerId'   : 'chart_div2',
        'dataSourceUrl' : 'https://docs.google.com/spreadsheets/d/1lmmpJs2Bz3EfQWExB4KXq_uJWoLlq1PMCahy6w4ipcE/gviz/tq?gid=942634171',
        'query'         : 'SELECT C, COUNT(C) GROUP BY C',
        'options'       : {
            'title'     : 'Neighborhood of Residence'
        }
    });

  neighborhoodChart.draw();
  }

这是正在使用的整个页面的脚本：

更新

理想情况下，我更喜欢仅依赖于更改查询本身的解决方案，因为这在语法上更简洁。我将在整个项目中多次这样做，并且希望避免涉及额外代码行的变通方法。

任何帮助将不胜感激。

这应该工作，必须是一个错误或什么...

'SELECT C, COUNT(C) GROUP BY C'

无论如何，您可以使用data.visualization.data.group手动聚合列

请参阅以下工作片段... 

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

function drawChart() {
  var query = new google.visualization.Query('https://docs.google.com/spreadsheets/d/1lmmpJs2Bz3EfQWExB4KXq_uJWoLlq1PMCahy6w4ipcE/gviz/tq?gid=942634171');
  query.setQuery('SELECT C');
  query.send(function (response) {
    if (response.isError()) {
      alert('Error: ' + response.getMessage() + ' - ' + response.getDetailedMessage());
      return;
    }

    var dataGroup = google.visualization.data.group(
      response.getDataTable(),
      [0],
      [{
        aggregation: google.visualization.data.count,
        column: 0,
        label: response.getDataTable().getColumnLabel(0),
        type: 'number'
      }]
    );

    var neighborhoodChart = new google.visualization.ChartWrapper({
      chartType: 'PieChart',
      containerId: 'chart_div',
      dataTable: dataGroup,
      options: {
        height: 240,
        title: 'Neighborhood of Residence'
      }
    });
    neighborhoodChart.draw();
  });
}
