在google visualization api中，此数据可用作单个图表。 https://developers.google.com/chart/interactive/docs/gallery/linechart

他们是2张图表的数据。每个用于尊重单个数据。我有2个数据。两个数据都有相同的数据。我想简单地创建一个包含这些数据的数组2.我怎么做。

我目前的意思是

['2013-12-17 Tue', 25]

＆安培;来自第二桌

['2013-12-17 Tue', 49]

我希望将其作为

['2013-12-17 Tue',25, 49]

我想添加第二个值。基于索引的所有日期都是相同的。我如何在Javascript中做到这一点。

Answer 1

首先，我假设数组符号为

var data = [['Date','first charts'], ...

而不是

var data = (['Date','first charts'], ...

您可以将“第二个图表” - 值导入data，如下所示：

for (var i=0;i<data2.length;i++) {
    data[i].push(data2[i][1]);
}

所以data[1] =＆gt; ["2013-12-17 Tue", 25, 49]

然后像这样创建Google可视化DataTable

  var dataSet = google.visualization.arrayToDataTable(data);

Answer 2

如果将这两个数据集导入DataTables，则可以使用google.visualization.data.join函数（documentation）创建合并的DataTable：

var dataTable1, dataTable2; // the two DataTables
// full join the two DataTables on dataTable1 column 0 to dataTable2 column 0
var mergedData = google.visualization.data.join(dataTable1, dataTable2, 'full', [[0, 0]], [1], [1]);

如何将第二个数组中的数据添加到第一个数组，以便在Google Visualization API中显示图表
