pgfplot 放大繪圖上的座標集並插入文本

pgfplot 放大繪圖上的座標集並插入文本

我已經成功地產生了一個漂亮的圖表,但想添加一個「循環」來放大我創建的特定閾值(第 95 個百分位)。在縮放圖片中,我希望能夠添加文字(以顯示 x 和 y 的值),這可能嗎?在下面,我設置了一個插圖,我希望它看起來像什麼,程式碼位於底部(抱歉資料點的數量)。

答案1

這個答案只是顯示了一些小的改進土撥鼠已經很好的答案。我定義要放大的座標第一的然後使用該座標添加紅色虛線,放置「間諜」節點並在放大倍率下方寫入放大點的座標。 (我還決定將坐標文本放置在以下放大倍率,因為這樣就沒有任何重疊。

更多細節請查看程式碼註解。
