I have a simple gnuplot script that plots a bunch of graphs. When I run it, it gives the following error:

EDIT: I've reduced the length of the code considerably as per the suggestions

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

I've spent a lot of time in trying to solve this. I'd really appreciate if anyone could help me on this. This is my code: 

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`"

问题可能pe_cnt不是数字，但您的测试用例不是自包含的（它从某个文件中读取此值），因此很难具体说明。

这是一个简短的、独立的示例，它使用相同的代码演示了相同的错误消息：

pe_cnt = "kittens"
set xtics add (pe_cnt)

利用

set xtics add (real(pe_cnt))

我猜，xtics add不会自动将字符串转换为数字，因为它在第一次遇到字符串时也允许使用不同的语法。以下是演员表：

set xtics add (pe_cnt pe_cnt)
