Question

我想要一个堆积的条形图。以下示例应为2017-W30堆叠两个值。相反，它在x轴上给了我2017-W30两次。

我在选项中使用了isStacked，但它无效。

'options': {
      width: '100%',
      height: 'auto',
      seriesType: 'bars',
      isStacked: true
    }

旁注：我稍后会尝试让一个球门线上班。这就是我使用'chartType': 'ComboChart',。

的原因

这是我的工作代码：

// Load the Visualization API and the corechart package.
google.charts.load('current', {
  'packages': ['corechart', 'table', 'gauge', 'controls']
});

// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(gChart0);

function gChart0() {
  drawChart();
};

function drawChart() {

  var divID_suffixFunction = '_TEMPLATE';
  var divID_suffixParameter1 = '';

  //var urlString = '../Logs/clnLogsCountingEvents?grade=All&SC=1&CauseSC=3';
  //var urlString_temp = 'https://jsonplaceholder.typicode.com/users';
  var urlString_temp = 'https://httpbin.org/get'; //source: https://resttesttest.com/

  $.ajax({
    type: 'GET',
    dataType: 'json',
    contentType: "application/json",
    //url: urlString,
    url: urlString_temp,
    success: function(result) {

      //Manually loaded "result" with JSON that normally comes from "urlString".   
      result = [{
          "prodID": 2,
          "calendarWeek": "2017-W29",
          "qty": 1,
          "goal": 5
        },
        {
          "prodID": 2,

        }
      ];

      //Create DataTable
      var data = new google.visualization.DataTable();

      //Add Columns
      data.addColumn('number', 'prodID');
      data.addColumn('string', 'calendarWeek');

与往常一样，非常感谢您的帮助！

isStacked选项堆叠同一行中每列的值

为了在同一周堆叠多个值，
您的数据需要与以下内容类似......

['calendarWeek', 'prodID 1', 'prodID 2', 'goal'],
['2017-W29', null, 1, 5],
['2017-W30', 2, 3, 5],

请参阅以下工作代码段...

  //Manually loaded "result" with JSON that normally comes from "urlString".
