這是什麼
將圖形概觀放置在放大的「詳細圖」旁邊。當使用者在概觀圖上移動視野時,於詳
細圖上顯示視野所見部分的細節。
何時使用
在龐大的資訊圖形(特別是在影像或地圖)中顯示龐大的資料集合時。我們希望使
用者能夠藉由大圖保持方向感,但也希望他們能夠拉近看到最小的細節。使用者將
瀏覽資料,觀察較小的區域或搜尋興趣點。遠處的概觀是有必要的,可以幫助尋找
這些興趣點,但是使用者不需要一次看所有資料點的所有細節 拉近觀看某個小
資料片段的細節,這樣就夠了。
為何使用
這是用來處理複雜度的老方法:利用一個遠處的概觀,以瞭解整體狀況;然後可讓
使用者拉近概觀、看到他們所希望瞭解的細節,讓遠處和近處兩種層次同時出現在
相同的頁面上,以方便反覆操作。
Edward Tufte 使用「
微讀數與巨讀數
」(micro and macro readings)一詞,為地
圖、圖表及 其他靜態資 訊圖形描述 類似的概念 。使用者一 直能看到大 型的整體結
構,同時也能夠依照意願觀察微小的細節:『視覺化的步調是緊縮的、緩慢的、個
人化的』。類似地,概觀加上細節的使用者可以有條理地捲動內容、直接跳躍、比
較、對照、快速移動、或慢慢移動。
最後一點,概觀具有「你在這裡」的路標指示功能。使用者只要看一眼概觀中的視
野(viewport),就可以輕易得知自己當下所處的位置。

QuotationMarkI wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.
