设置键（图例）坐标不起作用？

Question

我想将密钥移动到情节中间的某个位置，所以我按照教程并使用以下脚本：

set terminal postscript eps enhanced color
set title "Risk of the loan"

set output 'simulation.eps'
set xlabel 'Initial loan value'
#set key height 24
set key 8,0.7

plot 'simulation.txt' using 1:2 title 'Discounted loan value' with lines lw 3,\
     'simulation.txt' using 1:3 title 'VaR' with lines lw 3,\
     'simulation.txt' using 1:4 title 'CVaR' with lines lw 3,\
     'simulation.txt' using 1:5 title 'Probability of default' with lines lw 3

但是，当我运行它时，我得到：

ga1009@ga1009-dell:~$ gnuplot simulation.p

set key 8,0.7
        ^
"simulation.p", line 7: unknown key option

我做错了什么？

Answer 1

尝试

set key at 8,0.7
        ^^

在这里工作！
