Excel 中文本文件的自動導入/繪圖

Question

我運行一台機器，它輸出多個文本文件，我 plot，我有一個 VBA 腳本，它可以將我想要的所有文件導入 plot 從他們自己的文件夾中並將它們放在他們自己的工作表上。 我想知道是否有一種方法可以在導入它們時自動繪制它們？ 我需要為每對測試提供一個單獨的圖表。 那就是我有“測試 A-1”和“測試 A-2”，它們是相互繪制的，“測試 B-1”和“測試 B-2”在新圖表上等等。對不起，如果這令人困惑，我我對 VBA 仍然很陌生，並且會喜歡這樣的工具來讓我的生活更輕松一些。 我已經包含了我的代碼，它完成了下面的所有導入。 然后，每個文本文件（只是 xy 散點圖的數據）都有自己的表格，數據在 A 和 B 列中。提前為糟糕的格式道歉，我沒有寫！
