多個相連的圖像：標籤和頁面填充

感謝之前提出的問題Latex中如何用箭頭連接影像？

我能夠創建一組由箭頭連接的圖像。但是，我有兩個問題：

  • 如何標記每個圖像（在文本中參考圖 1.2 或 1.5）
  • 由於某些原因，產生的圖像會填滿整個頁面（視覺上超過半頁），或至少在圖像的同一頁上不允許任何文字出現。關於如何糾正這個問題有什麼想法嗎？

謝謝

答案1

如果你想堅持使用 a matrix，你可以簡化事情。首先，我將使用該選項matrix of nodes（您需要matrix為此載入庫），這使得設定矩陣節點的樣式變得更加容易。

然後，您可以使用目前計數器自動設定標籤figure（並向其添加 1，因為它僅在\caption排版後更新）並將您透過樣式提供的參數附加到它lablum。

請注意，已經可以使用特定的節點名稱來引用矩陣節點，例如矩陣左上角的第一個節點將是mat-1-1，因此您不需要定義自己的節點名稱，但因為您想要以boustropedonic 方式放置子圖形，我按照你的方式放置。

至於您的問題是圖形填滿整個頁面：這可能是由於子圖的大小造成的。嘗試稍微縮放它們。下面的範例顯示，如果可能的話，應將圖形放置在帶有文字的頁面上：

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix}

\usepackage{lipsum}

你可以讓蒂kZ/PGF 還可以完全自動為您計算標籤（您只需要事先以某種方式告知列數）：

使用該套件進行引用可能更容易subcaption，但是您始終可以創建自己的引用計數器（我創建了一個\refsetcounter基於計數器的宏\refstepcounter，但不是增加計數器，而是將其設置為在這裡派上用場的特定值）：

事實上，我不太確定你在追求什麼。如果您想保持標籤和標題可定制，也許這樣的方法可以工作：

我添加了一些樣式以使矩陣單元具有相同的大小。為了使這一點更清楚，我向要顯示的節點添加了一些顏色，您可以簡單地刪除它們（透過刪除fill=red!10）。

最後，使用該套件可能會更容易subcaption，但是，您將無法輕鬆地自由定位節點（例如從右到左）：

\documentclass{article}
