MATLAB不斷更新錯誤的圖形

Question

我真的很希望這不是一個愚蠢的小東西，我失蹤了，但我一直試圖找出這個東西了幾個小時了，並沒有取得任何進展。基本上，我創建了一個有3個子圖的圖。爲了整潔，我設定了一個功能，然後我製作了另一個不斷更新實時數據的功能。

問題是，在實時更新功能中，第三個子圖工作得很好，但現在我希望我的第二個子圖也能夠實時更新，但我還沒有完成。出於某種原因，每當我放入我的代碼訪問第二個情節時，它都會不斷更新第三個情節並寫作它！與此同時，第二個陰謀仍處於初始狀態...

這是代碼...我已經看了十億次，所以我現在處於虧損狀態，我不知道是什麼別人要做....就像我說的真的希望它不是愚蠢的大聲笑...謝謝一堆=）。

編輯：這是怎麼回事錯誤開始的部分地方說：「％刷新情節

在繪製任何內容之前，需要將第二個子圖設置爲當前軸。在繪圖命令之前可以使用axes(Fig.sub2)。
