linux - GNUPLOT:无效的表达？

Question

我有一个简单的 gnuplot 脚本，可以绘制一堆图表。当我运行它时，它给出了以下错误:

编辑:我已经根据建议大大减少了代码的长度

    ;
    set xrange [pe_cnt:range_high];
    set xtics xticks;
    set xtics add (pe_cnt) 
                                                                                 ^
line 26: invalid expression 

我花了很多时间试图解决这个问题。如果有人可以帮助我，我将不胜感激。这是我的代码:

range_high="`awk '{for(i=1;i<=NF;i++) if ($i=="--stop") print $(i+1)}' temp_info`"
xticks="`awk '{for(i=1;i<=NF;i++) if ($i=="--xticks") print $(i+1)}' temp_info`"
pe_cnt = "`awk '{for(i=1;i<=NF;i++) if ($i=="--pe_cnt") print $(i+1)}' temp_info`"
rd_cnt = "`awk '{for(i=1;i<=NF;i++) if ($i=="--rd_cnt") print $(i+1)}' temp_info`"

Answer 1

使用

set xtics add (real(pe_cnt))

我想，xtics add 不会自动将字符串转换为数字，因为当第一次遇到字符串时它也允许使用不同的语法。执行以下操作:

set xtics add (pe_cnt pe_cnt)
