gnuplot无意义打印错误

假设我有一个名为“test_gnu.txt”的简单数据文件，如下所示：

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 

我想画第一个数字和第二个数字。因此，命令将是：

使用1:2 t“标签标签”绘制“test_gnu.txt”

它给了我愚蠢的错误，结果与数据无关。怎么了？

你需要

set datafile separator ","

在你可以绘图之前

谢谢。我的问题是gnuplot教程通常太枯燥，无法仔细阅读！
