gnuplot废话密谋错误

Question

想象一下，我有一个名为'test_gnu.txt'的简单数据文件如下：

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 

我想绘制第一位数字和第二位数字。因此命令将是：

使用1：2 t'lablablab'

绘制'test_gnu.txt'

它给了我愚蠢的错误，结果与数据无关。怎么了？

Answer 1

你需要

set datafile separator ","

之前你可以画。
