Question

我有一个Google幻灯片演示文稿，其中包含与特定Google电子表格相关联的图表。

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图表，或者至少同时更新所有这些图表。

这样做的最佳方式是什么？

非常感谢！

Answer 1

您可以使用以下脚本将自定义函数添加到幻灯片UI中的下拉菜单中。这将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：更新/刷新链接幻灯片的功能在此响应时似乎不存在。

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

您需要为此编写脚本并按计划或手动运行。

我发现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的对象；出现的菜单底部的选项为“全部更新”。
