charts - 如何自动更新链接到 Google 表格的图表？

Question

我有一个 Google 幻灯片演示文稿，其中包含链接到特定 Google 表格电子表格的图表。

由于演示文稿中有许多图表，我正在寻找一种方法来自动更新所有这些链接的图表，或者至少一次更新所有这些图表。

做这个的最好方式是什么？

Answer 1

您可以使用以下脚本将自定义函数添加到幻灯片 UI 中的下拉菜单。这会从当前演示文稿中获取幻灯片，循环播放它们，获取每张幻灯片中的任何图表并刷新（更新）它们。

function onOpen() {
  var ui = SlidesApp.getUi();
  ui.createMenu('Custom Menu')
  .addItem('Batch Update Charts', 'batchUpdate')
  .addToUi();
}

function batchUpdate(){

  var gotSlides = SlidesApp.getActivePresentation().getSlides();

  for (var i = 0; i < gotSlides.length; i++) {
    var slide = gotSlides[i];
    var sheetsCharts = slide.getSheetsCharts();
    for (var k = 0; k < sheetsCharts.length; k++) {
      var shChart = sheetsCharts[k];
      shChart.refresh();
    }
  }
}

注意：在此回复时，更新/刷新链接幻灯片的功能似乎不存在。

您可以在有关 API 的官方文档中找到它（针对不同的语言）。 https://developers.google.com/slides/how-tos/add-chart#refreshing_a_chart

您需要为此编写一个脚本并按计划或手动运行它。

我发现我自己的代码效果很好。

最新更新：幻灯片的工具下拉菜单中现在有一个选项可以查看所有链接对象；出现的菜单底部有“全部更新”选项。
