柏拉圖（Pareto plot）結合百分比長條圖與累計百分比曲線圖，這類圖形常被應用於監
控產品缺陷的品管用途。[Page-495]
分位圖（Quantile plot）用來視覺化呈現兩組數據是否具相同的統計分布。若參考直線
愈接近繪出的資料點，表示兩組資料的統計分布愈接近。
PairwiseScatterPlot
指令將矩陣中的兩兩行資料作散佈圖，對角線的散佈圖形必為直
線。 以 下 使 用 2006 年 至 2008 年 間 的 道 瓊 工 業 指 數（Dow Jones Industrial Average，
DJIA）作為範例，圖形顯示 2006 年與 2008 年的散佈圖有接近反轉的趨勢，而 2007 年
中則開始脫離 2008 年的資料。
