範例：建立瀑布圖

繪製以稍微不同的值重複單一參數的數據。

2D 瀑布圖

將所有應變數值封裝成一個多欄矩陣，並將所有自變數值封裝成另一個多欄矩陣。此 2D 繪圖會將欄加以配對，並建立多條繪線。

1. 定義瀑布圖數據集。

2. 將列數與欄數指派給變數。

3. 將向量定義為第二個數據集。

4. 若要提供每個向量項目與每個矩陣項目的位移，請從向量建立矩陣。

將新矩陣的值稍微位移，以避免繪線重疊。

5. 繪製兩個矩陣。

不同長度的繪線

將空白項目封裝成具有 NaN 的陣列，以顯示不同長度的繪線。

1. 1. 將空白項目新增至矩陣。

2. 繪製新數據。

NaN 項目並不會顯示出來，因此在線條中會留下空白。

3D 瀑布圖

和 2D 繪圖不相同的是，您可以旋轉、平移或縮放來變更繪圖的檢視。
