條形圖的 x 軸標籤重複兩次

tag-icon • tag-icon tikz-pgf pgfplots bar-chart
條形圖的 x 軸標籤重複兩次

問題 1：我試著產生一個長條圖，每個圖表有 3 個長條。但正如您從下面的輸出中看到的，我的 x 軸標籤重複了兩次。 X 軸標籤 = {3-6, 6-12, 12-24}

問題2：當我在背面編譯程式碼時，我得到了完整的中心圖片，當我將程式碼貼到另一個文件時，它佔用了大量空間（因為整個pdf頁面正在複製到另一個文件）。有什麼方法可以讓我在編譯專案時只得到一個僅限於該圖像的 pdf 下載嗎？

誰能幫我解決這個問題嗎？

謝謝！

答案1

  • 您的問題並不完全清楚，例如，如何將此圖像插入到真實（最終）文件中？
  • 對於頁面上的圖形定位，請嘗試使用放置位置選項，即改為\begin{figure}寫入\begin{figure}[ht]或\begin{figure}[!ht]。
  • 在按照下面的 MWE 中的方式清理groupplot設定並重新組織圖形程式碼後，本地 MiKTeX 安裝以及 Overleaf 中的編譯會給出相同的結果。
  • 清理工作是按照我對您之前的回答的精神進行的問題（無需新增xtick選項）：

答案2

關於問題 1：添加帶有符號標籤的 xtick 命令（見下文）對我來說很有效。

關於問題2：如果我理解正確，將文章類從文檔替換為獨立對我來說是這樣的（我必須刪除圖形環境+標題）
