gnuplot 的图 - 缺失曲线

  • 772

正如预期的那样，下面显示了 4 条曲线：

    plot "a.csv"  using 1:2 lw 4 with lines, \
     ''       using 1:3 lw 4 with lines, \
     "b.csv"  using 1:2 lw 4 with lines, \
     ''       using 1:3 lw 4 with lines

但是下面只显示3条曲线：

plot for [flnm in "a.csv  b.csv"]     \
     flnm  using 1:2 lw 4 with lines, \
     ''    using 1:3 lw 4 with lines

“plot for” 命令中的错误是什么？

plot

    “for [xx=yy:zz]”仅适用于它引入的情节子句。你需要像这样的东西

    plot for [flnm in "a.csv b.csv"] flnm  using 1:2 lw 4 with lines, \
     for [flnm in "a.csv b.csv"] flnm  using 1:3 lw 4 with lines

    或者像这样

    plot for [flnm in "a.csv b.csv"] for [col=2:3] \
     flnam using 1:col lw 4 with lines
