Question

我正在尝试使用Google App Script / Javascript制作一个基于Google电子表格文件中多张工作表中提取的数据的信息中心。下面是功能代码，可以成功绘制八月数据图表。我想要的是将7月数据（表2）作为第二个系列添加到图表中。可能吗？

如果我能弄清楚如何存储和访问每个月的数据表，我想我应该能够使用.join()方法来合并这些表。 https://developers.google.com/chart/interactive/docs/reference?hl=en#join

提前感谢您的任何帮助！

这是一个可以解决我的问题的解决方案。如果有人有更好的解决方案，如果你能在这里分享，我将不胜感激。基本上，您可以在finished();函数末尾使用megaData(monthData)来规避异步javascript。所以结构看起来如下所示：

  function initialize() {

    var urlMonth = 'https://docs.google.com/spreadsheets/d/1dTeqpX1If74h5_I3POrYkoktSm7FxV47iSUHshhlmI4/gviz/tq?sheet=Sheet1&tq='
    var queryStringMonthly = encodeURIComponent("SELECT B, sum(C), sum(D), sum(E), sum(F), sum(G), sum(H) GROUP BY B LABEL B 'Issue' ");
    var queryMonthCurrent = new google.visualization.Query(urlMonth+ queryStringMonthly);
     queryMonthCurrent.send(megaData);

    var urlOneMonthPrior = 'https://docs.google.com/spreadsheets/d/1dTeqpX1If74h5_I3POrYkoktSm7FxV47iSUHshhlmI4/gviz/tq?sheet=Sheet2&tq=' 
    var queryStringOneMonthPrior = encodeURIComponent("SELECT B, sum(C), sum(D), sum(E) GROUP BY B LABEL B 'Issue' ");  
    var queryMonthOnePior = new google.visualization.Query(urlMonth+ queryStringOneMonthPrior);
     queryMonthOnePior.send(megaData);

  }

  function megaData(monthData) {
    //...
    //use codes from the question post
    finished();
  }

  function finished() {
    if (dataTables.length != 2) {
    //do nothing if data tables are not fully ready
        return;
    }
    //blahblah do something with all the data tables
   }

Javascript为绘制图表提取多个Google Spreadsheets数据
