本质上，我遇到的问题是图例与我试图绘制的 gnuplot 图重叠，如下图所示。
以下是我用来绘制数据的命令。
> set log y
> plot "datafile1.txt" using 2:4 with lines,
"datafile1.txt" using 2:6 with lines,
"datafile2.txt" using 2:4 with lines,
"datafile2.txt" using 2:6 with lines
以下是我用来绘制数据的数据文件 1 的一部分。
Dimension: 259 Timing: 36111 seconds, 9 seconds
Dimension: 260 Timing: 37860 seconds, 9 seconds
Dimension: 261 Timing: 39477 seconds, 6 seconds
Dimension: 262 Timing: 41215 seconds, 5 seconds
Dimension: 263 Timing: 41827 seconds, 5 seconds
Dimension: 264 Timing: 42738 seconds, 11 seconds
Dimension: 265 Timing: 42972 seconds, 14 seconds

Dimension: 273 Timing: 34616 seconds, 3 seconds
Dimension: 274 Timing: 36113 seconds, 4 seconds
Dimension: 275 Timing: 36477 seconds, 4 seconds
Dimension: 276 Timing: 37000 seconds, 2 seconds
Dimension: 277 Timing: 37872 seconds, 3 seconds
Dimension: 278 Timing: 42290 seconds, 6 seconds
Dimension: 279 Timing: 39862 seconds, 7 seconds
