设置键（图例）坐标不起作用？

Question

我想移动的关键，一些位置在小区的中间，所以我也跟着教程，并有以下脚本：

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 

然而，当我运行它，我得到：

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

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

我在做什么错了？

Answer 1

尝试这里

set key at 8,0.7 
     ^^ 

作品！
