我是 Gnuplot 新手,我正在尝试从输入的 .dat 文件构建图表。我的 .dat 文件中的第一列是一个类似于“内部版本号”的数字,我试图将这些数字用作其中一列的值。
对于这个 .dat 文件:
#Version-Number Average-Error Average-Performance
1 4.100333 41.76998
2 4.100333 41.76998
我得到正确的第 1 列和第 2 列。
但是对于这个 .dat 文件:
#Version-Number Average-Error Average-Performance
0.80.0.17598 4.100333 41.76998
0.80.0.17599 4.100333 41.76998
我得到如下列:0.792 0.794 0.796... 而我正在寻找的值(4.100333)落在 0.8 上。
这是我拥有的 .dat 文件:(称为 CompareResults.dat)
#Version-Number Average-Error Average-Performance
0.80.0.17598 4.100333 41.76998
0.80.0.17599 4.100333 41.76998
0.80.0.17602 4.100333 41.76998
0.80.0.17622 4.100333 41.76998
我附上了我的代码。
