gnuplot的廢話繪圖錯誤

Question

想象我有所謂的「test_gnu.txt」爲遵循一個簡單的數據文件：

0.32,0.116,0.398989898989899 
0.34,0.010,0.01212121212121212 
0.36,0.035,0.11313131313131312 
0.38,0.022,0.06666666666666665 
0.4,0.070,0.11919191919191922 
0.42,0.026,0.06565656565656566 
0.44,0.077,0.15858585858585858 
0.46,0.011,0.01616161616161616 

我要繪製第一位與第二位數字。因此，命令將是：

情節「test_gnu.txt」用1：2 T「lablablab」

它給我愚蠢的錯誤，結果是無關的數據。怎麼了？

Answer 1

你需要

set datafile separator "," 

，然後才能打印。
