如何在Google可視化查詢中將C列的值設置為字符串？

Question

如何從Google可視化查詢中得知數據C列是字符串？ 我在文檔選項中找不到任何地方可以向我展示如何將某些列指定為字符串或數字。 它認為C列是一個數字，並且在實際上假定將其設置為字符串時，在該列圖中添加了另一列。

是否在查詢選項或柱形圖選項中進行設置？ 我添加了儀表板和數據表的代碼以及圖片。

謝謝！ 布蘭登

我以前沒有以這種方式構建過DataTables，但是您可以嘗試使用setColumnProperty 。

我不知道創建后是否可以更改類型，但是值得嘗試一下這樣的嘗試：

data = response.getDataTable();
data.setColumnProperty(colIndex, "type", "string");
